Pregnant and boyfriend doesn’t want to have sex with me anymore 😔

I’m 19 weeks pregnant. My boyfriend and I have still been having sex throughout the pregnancy until around 15 weeks, since then it seems he no longer wants to sleep with me. He’s happy for me to give him a handjob (I thought this would just be foreplay...) but, won’t do anything more.

Today I couldn’t take it anymore and just cried afterwards, the lights were off so he doesn’t know and thinks I just went to sleep. I don’t really have a bump yet still, I just feel fat and disgusting
