I dont know if I should stay with my girlfriend when I go to college???

why don't you just think ahead in your future: Is she marriage material, or rather do you see yourself with her ten years from now? If not then theres really no point in continuing this relationship. If you want to meet to new people and shes holding you back, then well thats a problem. You need to live your life, and do what feels right. Go to the college you want, think of your future not about one relationship. You know what I'm talking about? Basically don't let someone hold you back, and if your not ready to move in w/ her, tell her. It could be a disaster waiting to happen!
