Husband doesn’t wanna have sex

I partially blame myself because I’ve become overly sex driven ever since my ex basically forced me into it so many times convincing me that that’s what love is is having sex etc. I do like to masturbate pretty frequently as well and that’s not a problem. However I would like to “do it” or be asked or touched like he wanted to do it once a week or twice a week. I maybe get it once a month. He had the other end of the spectrum where he would ask his exs once a month and they’d shut him down every time so he just gave up on asking. He asks me when he sees that I’m down and upset and I don’t know why that’s what he goes to. Also he masturbates a lot… like a lot which I don’t mind sometimes because we do it together sometimes and it’s fun but at this point it’s replacing me as well as just doing it just out of boredom. He’s using it all the time except for when he can see I’m visibly upset about other things. Like I caught him the other day and he stopped and I asked why he stopped and he said it was just reaction and he usually lets me join in on whatever when I catch him. But he flinched and legit stopped completely and got out of bed to go do something. I am emotional and 33 weeks pregnant. I know I’m fat rn etc etc. he will always say he loves me and I’m not fat or anything but I just hate all of it….
