Sex during pregnancy

Does anyone else's husband or SO refuse to have sex with you because they think it's weird you have a baby growing ? We have not had sex since I found out I was pregnant and we were trying for 9 months. I'm currently almost 26 weeks pregnant. In the beginning it didn't bother me because sex had kind of become a chore to have the baby but it really makes me feel bad that he doesn't even close to trying to have sex. I'm kind of worried that this will continue after the baby is here and that he won't look at me the same any more. He assured me that that's not going to be the case but I don't know it's hard to believe that.
