If he wasn’t gonna stay; why get me pregnant ?

This pregnancy wasn’t an accident. We talked about having a child and he agreed. I didn’t want to be like so many of my friends and get pregnant then have my bd move on to the next girl. He literally swore he’d never do that; even told my family he wasn’t going nowhere and since we been together five years, everyone including me believed him.

Now after me moving back home for barely two weeks, it’s hard to even get him to take my calls. We were supposed to be working on our relationship so we can give our child better parenting than we had. He showed up at my OB appointment today and I tried talking to him and asking what’s going on; now he’s saying I broke up with him; that me leaving was me breaking up with him and all we need to do is coparent. I started crying and getting upset because that’s NOT what I wanted. I left because he was never home; never paid attention to me when he was home. I get he is working two jobs but who wants to be home alone all the time and the only time I see him is when he comes home to sleep. He says he’s talking to someone else but that he plans on being there for his child. How can he do this in just barely 2 weeks and why would he throw our family away? And how does he have time to meet someone else when he’s supposedly working two jobs?
