I need help is a rough situation. Any advice pls?

I met a girl and I've been talking with her for sometime now. I'm attracted to her and I grew to love her, however she has a boyfriend (continue reading pls, allow me to explain). She trusts me and she told me that her boyfriend cheat on her, and since then her relationship has been toxic. I told her that she should break up but she still loves him and she thinks he is all she has. During her childhood her parents were awful and when she had the chance to leave her house she moved with her boyfriend when she was 17 year old. She attempted to kill herself when her boyfriend cheat on her, and she is very depressed. I really want to help her and I love her. I even offered her to move to my place if she leaves her boyfriend and she's been considering to break up in the recent days but she is hesitant. I don't know what else to do. She was really in need of help, she even said that if her boyfriend left her she would kill herself this time, but it seems I convinced her that suicide is never the solution. So I would like some advice on this pls, I don't know what else to do
