It was always an unlikely friendship, forged between two women who might more easily be cast as love rivals.

In fact Kathryn Dennis once went as far as to accuse Southern Charm cast-mate Jennifer Snowden of having an affair with Thomas Ravenel, the father of her children. It is something Jennifer has always denied though the pair did briefly date.

But for all their tumult Jennifer had come to view Kathryn Dennis as one of her closest friends.

Now, Jennifer, 35, has revealed that their friendship is over, having dramatically imploded when Kathryn turned on her, ignored her texts and calls and ‘bad mouthed’ her on social media, just when she needed her most.

Fifteen weeks into her pregnancy, Jennifer received the devastating diagnosis that her unborn child was suffering from a life-threatening brain encephalocele. At the reunion of Southern Charm, Thomas Ravenel, 53, responded to her plight with compassion and handed her a handkerchief

Speaking exclusively to DailyMail.com from her home in Charleston, South Carolina Jennifer said: ‘Kathryn and I pretty much haven’t spoken since the Southern Charm reunion (show) last June.

'I guess that was the first time the public got to see the real hearts of the cast and sadly that didn’t include the compassion of Kathryn who was supposed to be my friend.'

Fifteen weeks into her pregnancy, Jennifer received the devastating diagnosis that her unborn child was suffering from a life-threatening brain encephalocele - when the brain herniates extruding through a portion of skull.

The prognosis was bleak.

Jennifer was told most women choose to terminate the pregnancy but decided not to. She endured a high risk, high stress pregnancy with no guarantees of a happy outcome.

At the reunion of the popular Bravo TV reality show Thomas Ravenel, 53, set aside their differences and responded to her plight with compassion.

But according to Jennifer his sympathy and her acceptance of it infuriated Kathryn, 24. The volatile redhead, and mother to Ravenel's children, Kensie, 2, and one-year-old Saint, has not spoken to her former friend since.

Jennifer revealed: ‘I got emotional and Thomas handed me a handkerchief. I accepted it and Kathryn saw that as me showing allegiance to him and not her when what would have been nice would have been for her to reach out and hug me.

‘He was offering me compassion when I needed support, empathy and friendship from anywhere I could get it and it was shocking to me that it didn’t come from someone I had been such a good friend to.’

Instead, Jennifer said: ‘She had been bad mouthing me on social media because Thomas had been supportive and that infuriated her.’

Worse was to come as Jennifer discovered that much of Ravenel’s hostility to her stemmed from the fact that he believed her to be dripping poison into Kathryn’s ear about supposed liaisons with other women.

Today Jennifer believes that Kathryn was using her as a ‘scapegoat’ - telling Ravenel that Jennifer was stirring up problems between them when, as anyone who watches the show knows, Thomas and Kathryn are perfectly capable of stirring up problems for themselves.

Jennifer told DailyMail.com: ‘[Kathryn] was seeking a reaction from him in so many ways and telling him I had said things that just weren’t the case.

'I was asking her, “Why does he even think these things?” I blindly believe in the good in people but I didn’t know what she was doing. I was asking her, “Why does he think I’m saying these things?” She said she didn’t know. Now I know it’s because she told him and that, along with everything else, was the nail in the coffin of her friendship.

‘I know she was dealing with her own drugs and alcohol issues during this time but having gone through all this your tolerance for negativity is lessened to next to zero.

When Ascher was born in September, cast members sent her various gifts, but Kathryn didn’t even send her former friend a text

‘I messaged her all the time before the birth with no response. I would tell her, “I forgive you, I know you’re going through a bad place.”

'[Kathryn] demanded everybody treat her with kid gloves during her own pregnancy. She demands a level of respect that she doesn’t give another person on the planet and I just got to the point where it was enough. I wish her well.

'I don’t want anything bad to happen to her but I don’t have the energy left to navigate what it means to be her friend.’

When Ascher was born in September cast members sent gifts: matriarch Patricia Altschul and Whitney sent a sterling silver brush and bowl, Cameron gave a monogrammed pillow, Craig and Naomi gave a blooming bath, Landon gave a dream catcher made by her sister, Thomas a stuffed Jellycat toy. Kathryn didn’t even send a text.

'The women have spoken since but for Jennifer it was the end of the road as far as her close friendship with Kathryn is concerned.’

She said: ‘I’ve been nothing if not blindly supportive of her, sometimes to the detriment of other relationships, but you re-evaluate your friendships and what you expect from your friends and I realized that I was giving so much to being a good friend and was receiving nothing in return.’

On Tuesday, DailyMail.com spoke exclusively with Jennifer about the heartbreaking news of her son's rare brain encephalocele.

A specialist told her that 85% of women with the diagnosis terminate the pregnancy.

'She handed me the abortion papers and said you have eight weeks to decide if you’re going to terminate but we can book you in in two days time,' Jennifer said, speaking from her home in Charleston, South Carolina.

The fact that her son survived the eventual pregnancy, she said, makes him a 'miracle baby'.

‘Honestly at this point, after everything I’ve gone through, there’s not much that I’m afraid of anymore.

'I’m proud of myself and proud of Ascher. After I got the news I’d pray every night and I’d talk to my baby and tell him to be strong. I’d tell him you can rewrite what’s supposed to be a bad history,' she said.
