Needing advice about sexual aversion

I used to feel a lot of drive early on in my marriage. We have a 3 year old and another on the way. I am a couple weeks away from my third trimester and been really stressed from my job and I’m not sleeping.

I hate kissing or touching my husband with this pregnancy, I want to scream and run away. Last night he took me on a date and kept being horny telling me he really needed raunchy sex, feeling wanted sexually doesn’t feel good at all.

The whole time I was trying to have sex with him I felt like my skin was crawling and he would make comments that if I felt like I didn’t want it that it would hurt his feelings. He always says it hurts him and he feels resentful towards me because I don’t let him touch me whenever he wants.

I feel like I’m the jerk because I have to make sure he feels loved and gets his needs met because I’m his wife, but I feel like I’m pouring from an empty cup. I have PTSD from being sexually abused and his presence has started to feel suffocating. I don’t want to feel used anymore. Any advice aside from the obvious answer of get therapy?
