Need advise - should I leave my GF?

My gf and I (I'm gay) have been tog. for 7 mos. I moved to another state to be w/ her after 4 mos. We moved in quick bc I got laid off so we fig I start my job search in the new state. I didnt know that my gf drank everyday...and now is up to a bottle of wine a night. She has become mean and nasty towards me. Not only when shes drinking. Everytime I ask her what is making her so nasty she tells me its because Im not working. Truth be told I am working doing internet sales but its just some side money so I can give her half the rent. She constantly makes me feel bad about not havinga job and always says things like "If you really wanted a job you;d find one" Obviously I will not take a job that pays me the less or the same as unemployment that makes no sense. So she says she resents me for not having a job and the first job I did get I had to turn down bc the working conditions were horrible. I told her if you love me you wouldnt put conditions on your love for me. Last weekend we went out with her friends and she got drunk. She cursed me out, left her friends house, locked me out of the apt and when she finally let me in she let our maintenance guy call the cops on me bc she "wanted me out" and I technically am not on the lease. The cops came and of course they saw I lived there and left with no problem but who does that? Then she tells me she does love me and that we ar ejust having problems. I cant take it anymore an dI am deciding if I should I move back home. Problem is I love the old her. The woman who used to stare in my eyes and make me feel like I was the only one on the earth =( I dont foresee this getting any better but I've never been good at "knowing when to work harder or when to walk away". Please any advice is appreciated.
