Is it just me?

I'm 17 weeks pregnant. My husband has not been sleeping in our bed but in our spare bedroom. He has started talking to women from work and txt a and talks to them daily. When I've confronted him, he makes me feel like I'm overreacting. I asked him to go to my appointment tomorrow because he hasn't been to one with me and not even to my first ultrasound. When I was pregnant with my daughter he made it to every appointment he could when he got off the rig. He was there for ultrasounds and nsts. I asked him how far along I was and he said like 7-10 weeks. He's not ask excited this time around. He rolled his eyes and said yes he'll go tomorrow but I told him to forget it. I'm tired of feeling like I'm forcing him to spend time with our daughter and I. I can't ask him for help around the house anymore because he gets mad. On his days off, he closes his self off in the spare room and plays video games.  Idk what to do anymore. I'm at my wits end here.
