Am I overreacting?

My boyfriend lives in Chicago and I'm in New York and he's in school and im just working right now because we're having a baby and I'm taking a year off so I'm working all the time. I'm due in October and I just feel like he has no time for me. I understand he's stressed out with school but I feel ignored and like he's "too busy" for me. It's really upsetting because even a good morning/goodnight would be enough but I just feel upset. And sometimes he'll be on Facebook and I notice that he comments on his friends things but can't even text me back? Like idk if I'm being emotional or what but I don't say anything cause I don't want to argue idk what to do.
