Is it normal that i hate my family and current relationship

OK....To start I would like to say thank you to everyone that has read or commented to my post. This really important to and I really appreciate it, here goes. Its been about a year now, and I've come to realize that I hate my girlfriend, her kid, my mom, dad, brother and my friends. The only person I love is my dear sisters. These feelings started after I left college. My father is a self-centered whiny little bastard that thinks the world revolves around him and doesn't even care if I graduate college. My mother, bless her soul, puts up with this man to the point where she ignores everything that pertains her children. They refuse to help me pay for my education instead, buys nice cars furniture and other things. My brother, sadly doesn't want to go to college, has a child been to jail plenty of times, had his car impounded multiple times and my parents seem to shell out every dime they say they don't have to help him continue to screw up. My older brother if that helps. My "girlfriend" and I ended up getting together as a result of me moving away from my parents home. The plan was to only stay in the same apartment until I saved enough to move on my own, everything spilt 50/50.

The idea of splitting everything down the middle soon flew out the window. She ended up losing her job and I ended up paying the entire rent HER carnote and neglecting fixing my own car issues. She constantly drops the ball on simple things that she should be able to handle on her own. When her babys father lived with her she said she used to handle everthing on her own. Now it seemed like when I came into the picture she just decided to let things go. She found anther job that I ended up paying out of my pocket again for her to get to and also ended up losing that job. Her car note and rent and kid and everything else began to be to much for me handle eventually resulting in LOSING MY JOB AS WELL.

All I want to do is finish college and start my career and be left alone. She constantly throws this love b.s at me and I don't feel the same way at all. She like to say O you don't have to act like a dad then throws things in about wanting to live with me in the future and about her daughter loving me and all this stuff that I have no intention on thinking about. When I try to be honest with her she turns everything into my fault like I didn't explain what I wanted in the first place. This has driven me to despise her and her daughter.

I only moved in with her because when her kids father was kicked out she need help on rent and things like that so I agreed to split things down the middle. When things don't work out she puts me on a guilt trip and says me an my daughter will just sleep in my car ..boo hoo.. things like that and ends up sticking around.. I'm at my limit with my selfish disgusting family and with this girl only problem is IM STUCK NOW.

Her kid was never around this much and now she is around 24/7! She got into an argument with her childs dad and want me to be in the situation, when I really really could care less! So I have to sit in a home with a girl I can't wait to get away from and a kid that I have no feelings toward. I can't go home because its destructive to my future.

I've been slowly losing confidence in myself and what I should do. I can't keep on with this masquerade and putting forth these fake efforts, pretending like I enjoy this when honestly I hate my life and everyone in it, not including my sisters.

What should I do..I cant believe it has really helped me this much to type it out. Any and all feedback is welcome!!

Is it normal that I have all this hate toward my so called family and relationship..
