Break Up & Divorce

What am I to do at this point?

So me and my ex broke up about a 2 and half months ago and it was 3 week after I re proposed to her at her birthday party but anyway so since the break up I been fighting and tryna prove to her I can be that man I was before it ended vday past I cooked clean rub down for her etc. So we have to move out cause she don't want to start here and try to work on it or anything and I'm going to be homeless but we had night we cuddle talked etc. So Monday I come back home to talk to her because she called me and say she want to do it in person so I shot back to the house and she tell me oh I found a place so I said that fine but im still gon be homeless and living in my car so to make it worst two days later we talk again for her to tell me she was talking to a new guy since the end of January and she loves him as she say I crush me because I told her a. onth ago let's make a promise and she did the promise was if we are going to talk to anyone else we will let the other know but on my end I told her I don't want no other woman unless its you I'm a dj and work retail so you know how that can get but stay true to myself and sticking to it I always tell the woman no my heart is to someone already so for her to lie to my face it hurt big time and today I told her I'm done im move out in a day and we talked bout it again and she ask me if I call you in a month would you talk to me I said I don't know then she was like if I called you in 3 months and want to get back together would you I told her no you have a lot to prove to me amd she say I'm blaming her for everything but I told her your talking to someone else im not a option I can't hate or stop loving her im torn over her what should I do
