My Life Sucks!!!

I don't know what to do...my girlfriend has quit her job, leaving all the responsibility on me again. I don't know how she feels about anything anymore because she won't tell me and she's so moody and fuctup acting, nit-picking me to pieces about every little thing. I can't figure out if I'm just cursed to live a fuctup life or if I just need to get rid of her and move on. I hate people and their selfishness! :(
