Am I crazy??

I need someone's input from the outside because I don't know if I'm just being crazy or not. 
I love my husband and I know he loves me but I feel like he's not interested in me anymore. He knows that being this big is making me insecure. I've brought up having sex several times but he won't. It's been 3-4 months since he's gotten even slightly intimate with me at all. But he's real fast to point out when someone is "hot" on tv. Am I wrong to feel weird?
