Gamer boyfriend

My boyfriend is a big gamer basically addicted. He will play from about 7 pm until 2 am. Then will only watch 30 minutes of a movie with me before going to bed. It takes us 2-3 days to get through one movie. Now another issue is he keeps saying he wants alone time to be intimate after the kids go to bed but he has been putting that off. I'm starting to think it is because I'm 28 weeks along and maybe he just misses sex but can't bring himself to actually be with me. I was in an abusive relationship before meeting him and my ex didnt want anything to do with me during my pregnancies and he cheated so much throughout our marriage. He is making me feel so unwanted doing this and bringing up past trauma caused by my ex. After my ex I have set things I wont put up with and being treated like this is one of the things I refuse to deal with.
