Pray for my marriage

J • 27 and working on my second child. Full time medical assistant and going back to school for my RN.
After a year and a half and am 37 weeks preggo I think I am gonna be done with my husband smh. No communication and he left my son alone in the house without telling me. My son was with him all day. Or should have been while I am at work. He left him here so he can go back to his brothers house to play in his studio which he was there all day. Mind you we haven't had sex like he wanted to cuz he kept falling asleep after me feeding him. He hasn't done anything I have asked him but yet he wants me to do.what he asked. I am so furious I am waiting for him to get home as we speak. I don't know how to get through to him.
