Help!!! My girl wants us to Break?

o1st off I'm not gonna try and lie Ima tell it how it is. I met this girl at a job I had that I lost. We became cool and I moved into her crib. I lost my job but still had a truck and worked a lil bit with my grandfather. However she is the bread winner and pays the bills. This girl was so head over heels for me, I mean she loved me with all her heart. If I was tempted to leave she would grab on to me tight begging for me to stay. I've abused this, I've acted as if she dnt deserves a guy like me, I constantly put her down, I told her she eat too much, that her *** was flat, I tld her mean things about her family. I hurted her sooo bad continously. But she was holding on to that cool guy she fell in love with and I showed her another side of me. We been together for 3yrs and for 1 1/2 of em I showed her there was no hope here. She constantly wanted to talk things out but I didn't take it serious for I thought I had her and she will not leave. She entertained the idea of being single again and it made her happy. Now she wants us to go our seperate ways but I have no job no nothing. I'm freaking out, I can't go to my moms or nowhere. I did everything I could to let her know that I acted out of embarrassment cause I cldnt provide for her like I use too. But the damage was done, I've done too much to her. Her feelings aren't the same for.me anymore and all I can do is cry. I'm hurting yall, like all I want her to say is "Ok Man, let's work it out" but she already said that. She had time to prepare for this and not me, we lay nxt to each other and she will watch movies on her phone comfortably while I can't even concentrate on playing the game.because theirs a rollercoaster going on inside of me. Why did I do this, why was I so.stupid, I just want to love her more than anything ever. But I'm afraid its too late. She says that she loves me but needs to be away from me and if it was suppose to be we will come back together...(what type of bullish). She was down 4 me.
