Huma Abedin knew her husband was a pervert.

But she could not have known how his twisted sexuality would affect her own life - and the life of the woman she dedicated herself to.

Friday's dramatic disclosure by the FBI that they had found new emails relevant to their investigation into Hillary Clinton's secret server was a shock unprecedented in electoral history.

At the center of it, however, is the tragedy of a marriage wrecked by Anthony Weiner's addiction to sending sexually-charged messages and pictures to women - and a teenage girl - who he never actually met.

Weiner's world finally came tumbling down on September 21, with the dramatic revelation by DailyMail.com of his months of sexting a 15-year-old high school girl.

The way they were: This was the Anthony Weiner-Huma Abedin wedding's official picture - taken after Bill Clinton married them, seemingly anointing a new Democratic power couple

Rising star: Weiner was a Congressman for New York as Clinton ran for senator and flanked her in October 2000, shortly before her victory.

How it all began: The image Weiner accidentally uploaded to Twitter in May 2011, which he lied about claiming it was a hack. He came clear a week later that it was him

Sexting again: The next time Weiner was caught he posed as Carlos Danger, sexted Sydney Leathers - and prompted Abedin to stand by him publicly

Stand by your man: In the wake of the Carlos Danger scandal Abedin made a rare public statement of support, saying their marriage was not going to end over yet more sexting

He told her he was 'hard'; that he 'would bust that tight p****'; sent her unclothed pictures; and told her he had rape fantasies about her. Wiener knew she was 15 - the girl had told him.

At the time of the sexts, Weiner was still married to Abedin - although he complained about their lack of a sex life to the girl - and caring for their son while she campaigned intensively for Clinton.

New York police and the FBI moved in on Weiner quickly after DailyMail.com's revelations - and it now transpires that when federal authorities investigated, they took the former couple's shared laptop. It is unclear if they also took mobile devices.

In fact Abedin, 40, was already separated from Weiner, 52, by the time the FBI moved in, as she had announced the end of their marriage in August, when he was hit by another sexting scandal.

Abedin's loyalty to her husband had finally snapped; but it had lasted a very long time, endured a lot of scandals - and now, in the cold light of the FBI's latest move, must seem to her one of the worst decisions she could possibly make.

The foundations of the Abedin-Weiner romance were laid in Clintonworld.

Abedin has been Hillary Clinton's longest-serving aide, starting in the White House as an intern, not long after Monica Lewinsky was an intern too.

She has endured years of the Clintons' psychodramas, been at Hillary's side in the turbulent aftermath of the Lewinsky affair, and clearly knows everything about the Democratic candidate for the White House that there is to know.

She and Weiner started moving in the same orbit when her boss ran for New York senator in the dying days of Bill's White House; Weiner was the newly-elected representative in Congress for the 9th district of New York.

He first asked her on a date in 2001 - she apparently turned him down - then in 2008, as Clinton tried to be president for the first time, they began dating seriously.

Abedin, a devout Muslim, and Weiner, who is Jewish, were married by Bill Clinton in Huntington, New York in July 2010. Hillary had hosted an engagement party for them at her Washington home - the ultimate power couple seemed to be endorsing a new generation's Democratic power couple.

She was glamorous and impeccably well-connected, he was brilliant - an impassioned speech became a social media hit and he used the new technology to make himself one of the Democratic party's rising stars.

But it was less than a year later that Weiner became an international laughing stock thanks to that same technology.

In May 2011 a picture of the bulging crotch of a man appeared on his Twitter account; Weiner's response was to lie that he had been hacked.

A week later, he cried as he apologized for lying, and admitted he had had several inappropriate relationships with women online.

But he would not resign - and his wife was standing by him.

The next week yet more selfies emerged; this time he resigned, apologized to his wife - now revealed to be pregnant - and claimed he was seeking treatment for his problems.

It was little commented on then but it was Abedin's job at the time which is now the key to his role in the Clinton email affair.

While Weiner used his electronic technology to exchange sexts with strangers, his wife was using an email address from the now notorious Clintonemail.com server - despite being a State Department employee.

The next May Weiner was back - in a blaze of headline puns - running to be New York mayor; and Abedin was at his side.

'Look, I've made some big mistakes and I know I've let a lot of people down. But I've also learned some tough lessons,' he said in a campaign video.

For a while, it was going well; Weiner was frontrunner, far ahead of Bill de Blasio, the awkward-mannered ultra-liberal who is now New York mayor.

But in July there came a dramatic development: screen shots of more sexting that Weiner sent under the alias 'Carlos Danger'.

The recipient was Sydney Leathers, a 22-year-old from Indiana who had never met Weiner.

Once again, Abedin stood by Weiner. This time she did it in public, saying that although he had made ' horrible mistakes, both before he resigned from Congress and after', their marriage was secure.

'What I want to say is I love him, I have forgiven him, I believe in him, and as I have said from the beginning, we are moving forward.'

Weiner, hardly surprisingly, lost the mayoral race, but that was not going to change his conduct - or his wife's loyalty. Their marriage was increasingly like the Clintons', a cycle of sexual scandal on his part followed by loyalty on hers.

Next June, 2014, he was back in another collision of sex and twitter, favoriting a tweet which called Tinder the 'ultimate sext machine'. He apologized; Abedin stood by him.

By 2015 it was Abedin who was the couple's leading figure, with her place at the side of the presumptive Democratic presidential candidate, profiles in magazines, and a guarantee of a place in a second Clinton White House.

Weiner was at home with their son Jordan, tweeting non-stop, and with little real work beyond occasional media appearances. At one point in the summer of 2015 he took up a job with a PR firm. It ended when some of the partners left in disgust.

What I want to say is I love him, I have forgiven him, I believe in him, and as I have said from the beginning, we are moving forward Huma Abedin - July 2013

Abedin, a constant presence in Clintonworld, was constantly on the road with Clinton but in early 2016 came another distraction from the campaign - this time the Sundance Film Festival debut of Weiner, a documentary of his attempt to become mayor.

It she fresh light on their marriage and many critics noted how it seemed that far from being a Clinton-esque political pact, Abedin was genuinely hurt by the Sydney Leathers episode, wolfing down pizza as she tried to keep her composure.

Weiner reacted to the spotlight as only he can: being caught in a sexting scandal.

In August, his latest disgrace emerged. This time he had sent a picture of himself in bed, clearly aroused, with his son sleeping at his side.

The picture from July 2015 was to a 40something divorcee who replied: 'You do realize you can see you[r] Weiner in that pic??'

Finally, it was enough for Abedin and she ended their marriage - although neither moved out of their apartment near Manhattan's Union Square.

'After long and painful consideration and work on my marriage, I have made the decision to separate from my husband,' she said.

'Anthony and I remain devoted to doing what is best for our son, who is the light of our life. During this difficult time, I ask for respect for our privacy.'

She was quickly back on the trail with Clinton, and if frosty with reporters, always present at Clinton events, and clearly supported by her boss.

It's over: The estranged couple were photographed just hours before DailyMail.com's bombshell revelation of his sexts

T-Dog: In the messages, which were obtained by the Dailymail.com, Weiner repeatedly complimented the girl's body, told her that she made him 'hard'. He also sent the girl a selfie from a hot tub

Weiner and the girl used several anonymous messaging apps, like the one pictured above, where every line of text - and the sender's name - disappear after the message is opened. In one message he told he would 'bust that tight p***y so hard'

Huma Abedin and Hillary Clinton spoke on board Clinton's campaign plane just hours before news broke on Friday that the FBI was re-opening its investigation into the presidential nominee's emails after new emails came to light during a separate investigation into Abedin's husband, Anthony Weiner

The former couple are assumed to have started the task of unraveling their life together, but then, in September, came a bombshell which put the past sexting in the shade: DailyMail.com's revelations of sexual messages and pictures to a 15-year-old girl - at a time when he was married to Abedin.

He carried on a months-long online sexual relationship with a 15-year-old girl during which,she said, he asked her to dress up in 'school-girl' outfits for him on a video messaging application and pressed her to engage in 'rape fantasies'.

The girl, whose name is still being withheld by DailyMail.com because she is a minor, said the online relationship began last January while she was a high school sophomore.

I would bust that tight p***y so hard and so often that you would leak and limp for a week Anthony Weiner, 2016 - to a 15-year-old girl

Weiner was aware that the girl was underage, according to DailyMail.com interviews with the girl and her father, as well as a cache of online messages.

This time Weiner was T-Dog - and an avid user of the sort of instant messaging technology which does not leave a trail. Precisely the sort of technology Clinton had once joked she liked, in the wake of her email scandal emerging.

In the online messages, Weiner, 51, sent bare-chested photos of himself to the underage girl, repeatedly called her 'baby' and complimented her body, and told her that he woke up 'hard' after thinking about her, according to copies of the conversations.

In one particularly lewd message, he told the teen: 'I would bust that tight p***y so hard and so often that you would leak and limp for a week.'

When confronted with the claims, Weiner did not deny exchanging 'flirtatious' messages with the teen. He declined to comment on the specifics of the allegations on the record, but provided copies of two emails the girl sent him that he contends raised questions about her claims. DailyMail.com publishes them below.

He gave a statement to DailyMail.com in which he said, in part: ' I have repeatedly demonstrated terrible judgement about the people I have communicated with online and the things I have sent. I am filled with regret and heartbroken for those I have hurt.'

In Clintonworld, there was no comment, and although Abedin was not on the trail in the immediate aftermath of the story, she was soon back at Clinton's side.

She may have thought that ending the marriage would keep her safe from the fallout from the revelations.

But on Friday she learned that Weiner's fallout is now a danger not just to her - but to Clinton herself.

The FBI had long since said that Clinton - and by extension Abedin - would not be prosecuted for their handling of classified information on the secret email server when an entirely different investigation was launched, this time into the sexting.

What became clear within hours of the dramatic announcement by the FBI Director James Comey on Friday morning that there were new emails relevant to the investigation was where they came from: either Abedin or Weiner's devices.

Both, a New York Times report made clear, had been taken by the FBI in the course of their investigation - and the new material was found.

Abedin was seen just a few hours later, once again at her boss's side, and once again inscrutable.

Now she has just 11 days to find out if the man she stood by as he betrayed her over and over again has turned his insatiable lust for electronic sex into a fatal blow to the Clintons' dream of returning to the White House.
