Need help with my ex girlfriend situation..

So today is Monday and me and my g/f broke up on Friday. Heres what happened: I was over at her house like I normally am, we spend almost every night together for the past 3 months, I was using my laptop and decided to run to the store really quick, I did not turn off my laptop so it was still open to my myspace home page. While I was gone she went into my inbox and read a message I had written one of my friends over a week ago saying that I was confused about the relationship, she was treating me like shit, and I called her a B*, (in the e-mail). When I wrote the e-mail I was upset about something that had happened and was simply venting to him, I didn’t mean the things I wrote I was just trying to get my anger out, and all the e-mail said was that written above. So after reading the e-mail I get back from the store, still having no idea what was going on and she told me we needed to talk. She went on to tell me that it made her feel horrible that I felt that way about her and that she didn’t want to be with me anymore. I pleaded with her for 2 hours, even held her for 1/2 hour until she said she wanted to sleep and I said I’d leave. So I didn’t talk to her all day Saturday, and then a couple of our mutual friends have tried to fix it and she is telling them that she thinks we’re going to work it out. Well then Sunday night there was a dinner set up, and she didn’t want them to tell me she was going, so I was hopeful, thinking wow what a great surprise. When she showed up she was super drunk, but she was very touchy feely and kept calling herself my g/f. We decided she was too drunk to drive home and so while another friend took her home I went to her apt so I could drive him back to his car, I walked her to her door and used my copy of her apt key to let her in and she kissed me, not a long passionate kiss, just a normal peck, and she told him that she had a lot of fun and she hoped I would call her and ask her out again. I don’t know what to do, I love her with all my heart and I am pretty sure she loves me, I just think she wants me to be the one to fix this again like I have in the past when we have gotten into little arguments, but I don’t think I should have to fix it this time, that she should since she is the one who screwed it up. What I am afraid of is that she will just give up if I’m not the one to try and fix it, Please help I don’t know what to do. I should mention I am female also.
