Am I wrong to feel this way?...

My boyfriend is always going out with his friends whether it be going to play basketball or go to there house and play poker. I'm always stuck at home with nothing to do and he's always leaving with his friends. I am 37 weeks pregnant and there's really nothing I can do and my car isn't working and he's always just leaving me. I hardly complain when he goes because I know he needs time with his friends but just right now he told me he wanted to go play basketball with his friends and i got a little upset and told him "go you always leave anyways'' and he went. I know that was a little out of line but I want to at least spend some time with him before my baby girl comes. It's our first baby together but idk if I'm making a big deal about it...
