Sex advice plz😪

So me and my partner was just about to have sex when it went in I got a sort of flash back of being raped before and I moved and started crying. I said I don’t want too we can in a minute. He went straight into a mood and didn’t talk to me as I carried on crying he asked what’s up then was getting angry I didn’t answer him so I said I just thought of bad things and he was like serious I reminded you of them (as he knows what happened) walked off to have a joint while I’m still in bed crying comes back and says I’m going first thing in the morning. I’m his sad is it selfish of me to think he would of comforted me I just wanted too be told it was ok. Currently

On the sofa don’t no what to do☹️ I’m 32 weeks pregnant also 😥
