I want sex just not with my SO

I feel so horrible, my husband has been so supportive throughout everything and I'm almost 6 weeks pp and he's been dying to get intimate with me and I have the sex drive I just don't feel the connection with him. Before I wanted to tear his clothes off when he would come home from work and now he doesn't turn me on and I can't shake it.

Please tell me I'm not the only one feeling this way.
