Feeling unwanted

My husband is always eager to go to the gym each night or try and go out with friends at night on the weekends lately…. Im 33 weeks pregnant and we haven’t had sex in over 2 months… each time I’ve asked there’s a excuse “well ur back was hurting I don’t wanna hurt u” “ur pregnant” “I’m gonna go play video games”…. It just seems like everytime I ask I get shut down. He waits me out till i go to bed. It’s just odd to me. We don’t go out on dates or anything anymore and don’t really even spend time just the two of us. If we do it’s because he needs my help with something. So I told him how unwanted I’ve felt and it got turned back on me… I’m just so frustrated. I try and make time for him and not even in the sexual aspect just time in general but get shut down.
