Advice anything

My husband and I have been married for awhile now and our Anniversary is tomorrow. We've been arguing a lot over sex and how I haven't been in the mood. He says he's stressed and sex helps but to me it doesn't and I can't have sex when I'm stressed. We are also pregnant so that is part of the reason why I don't want sex lately. Is there something we can bond over other than sex? We watch netflix together but we hardly touch or kiss :/ our relationship is dying. We don't say hurtful things to each other just don't really show love to each other either. I want it to feel good when we are together again. I want us to be happy and to enjoy this special moment in our lives. But we are always stressed, tired and exhausted. I want to make us happy again but I don't know how to.
