Covered during sex

My husband and I haven't had sex in 2 months. He works nights and overtime and says he only gets in the mood at night... so it's been rough. We finally had sex today in the afternoon but he suggested I was completely covered up with a heavy blanket... I noticed he couldn't even look at me when I was giving him oral.

I'm pretty sure he's no longer attracted to me. He works with a lot of really fit women so I guess I can't really blame him since I'm heavier now and pregnant.

I'm not even going to try to have sex anymore. This killed it for me.

Anyone else in my situation?
