Life Decision

Anyways.. I'm going to be working and going to college but my parents want me living at home instead of with her and her mom and step-dad. My girlfriend and her family want me to live with them and I feel like that is the right choice but my parents told me they won't support me or talk to me anymore if I move out with them. I don't know what to do. In no way would I be living off of her parents because I'd chip in for groceries and pay rent for myself because of my own pride, but I just don't know what to do. I know the right thing is to be there with my girlfriend and my baby whenever I'm not working or in class but my family wouldn't talk to me anymore.
