Hayes, 21, revealed that the insults the 22-year-old Middlesbrough star heaped on her drove her over the edge, plunging her into a black mood and making her feel she could not go on.
Heartbroken, she downed a cocktail of four bottles of wine, four boxes of painkillers and a bottle of sleeping pills after a row turned nasty.
"I thought: ''I can''t make Matt happy, I can''t make anyone happy, I can''t do anything right, I can''t even make my stupid self happy, so it''d be much easier for everyone if I''m not here''," the Daily Star quoted her as saying.
"If there was a switch I could turn off I would have done, I just didn''t see any point in me being here," she said.
Hayes throughout the interview kept getting calls and texts from Bates, and he could even be heard yelling at her through the phone.
Just a day after her suicide bid, Hayes looked edgy and in a state of shock and was far from looking her glamorous self, as she revealed that her relationship with the footballer was peppered with violent outbursts.
She claimed he once smashed her phone to stop her talking to anyone else and flung her across a room.
During the interview there were evident bruises on her arms and legs, which she said had been caused by Bates pushing her around during their final row.
"It''s the things he said that hurt the most," she said.
"He was constantly belittling me, manipulating me and picking on things I''m insecure about," she recalled.
When Hayes decided to end their relationship, after she found messages and naked pictures of other girls on his phone, he bombarded her with presents and balloons, begging forgiveness and denying he had cheated.
And on the day of her overdose Hayes went to his house after deciding to give things another try - but was devastated to realise he had not spent the night there.
She fled to her home in Wakefield, West Yorks, but Bates followed and barged in, she claimed, starting a row that was so loud her neighbours came round.
Things turned even more ugly when, Hayes alleged, he picked her up and physically tried to drag her out to his car.
"He was screaming: ''You''re pathetic, even your friends don''t like you. Is it any wonder I''ve been texting other girls when I''ve got someone like you?''," she revealed.
"After he left I was thinking: ''What''s wrong with me that people have to cheat on me?'' I did everything he wanted, I cooked for him, I didn''t do hardly any glamour shots because he didn''t like it.
"I had some wine and thought I really can''t be bothered with this any more. I can''t look in the mirror and see anything positive," she recalled.
After swallowing the pills and drink, she lapsed into unconsciousness but was saved by a pal who went round after being worried by a nonsense text she sent in her drugged confusion.
"I woke up with tubes sticking out of me," she said.
"Matt came to see me and had a go. He was saying: ''You disgust me for this. You should have finished what you started. You''ll end up with no-one and only have yourself to blame''," she said.
Hayes revealed she has been plagued by angry phone calls ever since as he urges her to stay silent.
She claimed that during their fraught relationship, Bates forced her to delete men from her phone and Facebook account and publicly branded her a "slut" for chatting to a male pal.
"I can''t stop loving him - I thought we would get married and have kids. But by talking about what''s happened I''ve drawn a line under it," she said.
"I''ve got so many issues I''ve got to deal with - I need to get some help," she added
