Just sat down to watch a movie with my boyfriend. I'm 5 months pregnant with our first child.

We have been dating for almost 3 years and were living together for 2 years. We both just graduated college. I was at school for a few hours on Tuesday getting my student ID and just class shopping. I had my doctor appointment today and found out we're having a baby boy. On our way home tonight, we decided to stop for dinner. We met at the restaurant (he got there a few minutes before me) and the first thing he says to me is he can't be a father. He's telling me that he doesn't want to be with me if I plan on being a mom. I'm so heartbroken, I'm 24 and he's 25 and we both have good careers. I thought this is where we were headed but it looks like we aren't. I told him I think we should break up because of this but he said that he'll give it another shot but he might not want to be with me anymore. We're watching a movie on the couch rn and he doesn't know I'm writing this. I'm heartbroken. I never thought we would have problems and we've never argued until now. He just seems so cold and distant. I told him that I'm just going to do it on my own if he wants to leave me. I would have never expected him to say he can't be a father. He's really smart but he's never been the best with people. What options do I have after what he said?
