To I do too much for her?

I'm 17 and graduating at the end of this week. I still live with my parents and she(my girlfriend) lives with her parents and our daughter who's 7 months. She graduated last year so she stays at home with her all day. Im just getting pissed off because 'I've worked five days a week while going to school all year and over last summer. I have my own car and I let her use it all the time to see her friends and stuff but she'll run the gas out of it and not even bother to help. I see our daughter all of the time and sometimes I'll get out of work and she'll ask me to come over when I just want some time to myself. I want to go to a community college next year but I'm not sure if I can do that because she's so needy, I don't want to be a dick but she yells all of the time about me screwing something up when I honestly think I'm doing more than she does. I'll go to the skatepark sometimes Friday night and she'll text me the whole time calling me a "neglectful asshole" to tell the truth I don't want to be with her at all but she's the type of person who wouldn't let me see my kid at all.
