am I overreacting

My boyfriend and I get along so good. He's my best friend of course. The thing that drives me insane is when we do happen to fight or I happen to get mad cuz it's always me because the things he does drive me crazy sometimes but anyhow he seems to ride along with it. Like he won't talk to me, he will sleep in his daughters room or the couch, and he will come home whenever it's convenient for him. He just goes with the flow of me being upset or mad instead of talking to me about our problem. So I got upset with him Saturday so he slept in his daughters room of course and then wakes up around 10 and bounces. He didn't call me or text me all day Sunday. It's now Monday 9:30 am and he still isn't home. He didn't come home at all!! Makes me more mad and frustrated and sad and so many emotions. Add I'm 35 weeks pregnant. And FYI his daughter his only here sometimes cuz she lives with her mother and that's why he sleeps in there. But am I overreacting about him not coming home? And I wasn't worried about what if something happened cuz they check his fb to see when the last time he was active and he will be active all the time but just never have time for me. Im ready to move back with my mom because I feel more stressed here. Any suggestions?
