Babies last name.

Me and the boyfriend live 2 hours apart and we are having serious issues. He wants to be there for the baby when it comes to the cute stuff but when it comes to bills and helping me buy baby stuff he doesn't want to partake in it. I realize he needs things at his parents house but not nearly as much as me because I'll have the baby most of the time. I make pretty decent money but he makes a lot more than me and I pay a lot more bills than him. (He lives at his parents, rent free) I already see us breaking up and going to court. So I'm having a dilemma of whether I want this baby to have his last name or mine.
