I need someone to talk to 😔

I found out I'm pregnant today!!👶🏽 but my boyfriend an I have been fighting a lot. I told him he's supportive and happy. Lately he hasn't been coming home he stays at his sisters house or his friends house!! I know he's not cheating but it's the fact that I'm at home by myself. And he doesn't see anything wrong with it. And thinks I'm mad over nothing so we broke up and he came and got his clothes today I don't know if I'm just trippin and over reacting or is he in the wrong.
