I need some advice!!

I’m currently 28 weeks pregnant, and for the past few weeks my husband has not been in the mood.. I’m always in the mood and when I’m wanting to have sex it alway “I’m tired” “im not in the mood” and so on.. well it started making me think the worst.. am I not attractive anymore, is there someone else?? What?? Well tonight he finally talked with me about it because it gotten me so worried and stressed/depressed. He says it has nothing to do with anyone else, he doesn’t want anyone but me. He says when he sees me he sees his child, he sees the mother of his child, and he doesn’t want to hurt the baby.. he said it has nothing to do with the way I look, that I am beautiful to him, that I’m glowing in his eyes.. he said he’s never Experienced this feeling before and talked to a couple of his guy friends to see if it was natural to not want sex while I’m pregnant, and they said it was perfectly natural.. I mean I understand in a way but then I just don’t know.. so please y’all help me out with your opinion about this.. what should I do to maybe kick the mood in or something....
