What should I do? What can I say?

Me and my SO are in a fight right now. So, anything he has fucked up or and made mistakes I always give him another chance or at least let him explain himself.. why doesn't he do the same for me? On Tuesday I was pissed at him bc he gave this girl that was obviously trying to talk to him his number, I let him explain himself and I know he didn't necessarily have bad intentions, but it was just stupid! at the end of the day we were supposed to go to couples counseling but since I was still frustrated with the situation and I was still in a bad mood, he decided to bail on me. I always look forward to going because we always come out stronger and I knew that if we went things would be cleared up and we may have some kind of peace.. I was so angry that he didn't show up and wasted my time and our therapists time. So when I got home he started packing his shit and I just flipped... I lost my shit and knocked over some clothes and he told me "fuck this family" (I'm 24 weeks pregnant). I told him I hated him a couple times and since he's leaving the apartment, I would move back to dDallas. I told him that things will be different with this baby because I'm not a part time mom like my step daughters mom and not to be surprised if he doesn't see us as much. In the midst of everything I accidentally knocked over a water jug on his clothes and it just got heated. He went to his moms house and still won't come back home. I never kicked him out and I think it was wrong of him to say fuck our family not show up for therapy... but I shouldn't have been so immature by knocking stuff over. He's really just mad because of me saying I hate him and how I said if we aren't together he won't see our daughter all the time like he does our step daughter (I would have to move back home bc I can't pay rent and bills by myself right now). He won't return home and says he's not going to talk or come home until I go to anger management and I hurt his feelings.. I understand I said hurtful things but I am also hurt... I love him very much, and have let him make it too many times but when it comes to me fucking up he is just cold.
