Feeling insecure.

Ive been feeling super insecure lately. Im 21 weeks and looking more like a beached whale everyday. I know my husband cant be attracted to me anymore. He used to tell me everyday that i was beautiful and now he doesnt even tell me once a week. I see him looking at other women who are prettier with better bodies. He tries to play it off but i know what he is thinking. I just want my body back. I want to feel like my husband actually wants me rather than just being there because we are married.
