Exhausted!

Im 35 weeks pregnant. I'm 19 years old FTM I'm just so overwhelmed with this whole pregnancy I don't really have anyone to turn to but man this pregnancy has been nothing but drama with the father of my son. Just everything I feel like I've been so nice to him I let him come back to my life when he left me for another girl. And he doesn't even seem to care about his son he says he does but he hasn't bought anything for our son. I just don't know what to do anymore. 😔 I want my son here more then ever I just don't know what to do with the father of my child.
