Winning back my ex girlfriend

Hi all. Really need some advice. I met my girlfriend 3 years ago and twice this year we have broke up. The first time back in May this year, i emotionally shut down and did nothing but moan. After she spoke to her ex she walked out. Her and her ex have bad history and her family dis approve because of how violent the ex was 9 years ago. Yes was communicating with her ex for 4 weeks until we got back together. 5 months later she spoke to her ex again and again walked out saying she wasn't happy. It has been 8 weeks now and i know she is back seeing her ex despite her sons disapproval (one son has disowned her because of it) Her ex lives 3 hours away and far as i know my ex goes to see her every couple weeks. My ex never really gave me a proper reason why she left and did it by text message as she did in May. I hate to say it but the communication between us has got really nasty. I know i should have left her to her own devices for a while but i couldn't. She says she hates me but i don't believe that.
I am now trying not to message and perhaps contact her when all calms down. I am really struggling with it,finding it hard to focus because i love her.
I find it hard to believe this would work between them as not only was it a bad relationship 9 years ago,she is set to upset hr whole family,especially her 2 sons as they went through it when they were younger and cannot forget. She says she has no plan on moving back to her ex,she has a life here and a good job. She is the type that seeks excitement all the time and believe that her ex offers her that at the moment.
I have done and said some horrible things and am currently getting help for my issues. I have threatened to lose her job for her,communicated with her sons about her which she was angry about. I know i have been wrong but i didn't handle my emotions very well.
I don't know the best way to make her realise i am sorry and i did this all out of anger and sadness. I know she said she hates me but i just think its anger. Few days before she walked out she said how much she loved me,had same sort of comments back in May which she admitted she just said that and didn't mean it.
Any advice on what i should do please? I know most will say move on but i love her and feel when all this has calmed down i should reach out to her one last time. Just not sure how long i should leave it before trying et.. Thanks for reading
