There is a lot more going on here than what initially seemed to be. I'm not sure many people on here are truly qualified to offer a proper solution.
Sounds like some serious incompatibility. Some people feel that they should still be together though even if 80% of the time they don't get along. Counseling could be the solution, although personally I don't think I would ever do it.
I don't think you should be accusing her of wanting you to leave. That's just more and more pointless mind games. You seriously need to sit her down and ask her "are you happy?" with who she is, with you, with the relationship. Ask her if there is anything she feels she needs from you that she isn't getting. At the end of the day if she is your partner you need to be caring, considerate and understanding. There may be things you do, or don't do that really piss her off and she responds by getting drunk knowing you don't like it etc. Where as its the communication that's broken down.
