WARNING: SOME PEOPLE MAY FIND DETAILS IN THIS INTERVIEW UPSETTING

Matthew Myles remembers the moment he won £1 million well; the feeling of his fist clenching after entering his numbers online.

But after going travelling for eight months, the 29-year-old suffered an attack which he won't forget either, by his ex-girlfriend.

She's now been found guilty of assaulting him and in his first broadcast interview he's told Newsbeat his story.

"We had quite a good start to our relationship everything seemed fine," he said.

They met in 2013, went out for 10 months, then split up early last year.

Matt, from Hereford, remembers her changing over time.

"She'd make little jibes about my physique and what I was like as a person."

Within three weeks of their on-off relationship ending, Matthew was celebrating winning £1m on the EuroMillions.

But once he'd returned his ex-girlfriend got back in touch.

"When you win that amount of money and it is very public, you become very distrusting of people.

"She was what I knew. Looking back I was a fool for doing it, but I trusted her."

He says she tried to convince him she had changed, but he realised her behaviour had got even worse.

"She used to take her shoes off after a night out and launch them at my face. One time she grabbed me round my throat after a night out as well.

"You kind of just shrug it off because it's not a serious incident. Obviously I didn't realise it was going to become this serious."

Things did get serious, when one night he had to take her home after she'd drunk too much on an evening out.

"I got a Snapchat from a girl that I've never met, and it was just of her drinking a glass of wine.

"So at this point she hit me in the face and she's got quite long acrylic nails and she scratched them down my neck and drew blood."

As Matthew tried to get her out of his house, he realised he didn't have a key for his door to lock her out. She tried to get back inside.

"I tried to stop her, she then pulled my testicles and wrenched me down to the floor, splitting my scrotum sack.

"If the shoe was on the other foot, I know full well I would have got a custodial sentence."

Matthew has since been heckled by some people for being abused by his girlfriend.

"I think people should know this does happen, and you shouldn't keep it behind closed doors because it can get serious and it can get worse."

His ex-girlfriend was found guilty of two counts of common assault, and one of criminal damage.
