PPD or is my relationship failing

I’m 3 months pp with my second. I feel like I have lost my self identity completely. But I feel like I have lost my relationship with my husband. We still haven’t had sex since baby. Mostly because I don’t want to. I’m not attracted to him and there is no connection at all. Even when I tell him I feel like we don’t have a relationship he doesn’t acknowledge my feelings. Instead gets mad that I can’t put my finger on why I am feeling this way. The only thing I can think of is PPD. Another reason why I feel like I may have ppd is because everyday when I wake up I really just wish the day was over already. It’s just too hard. Could ppd be hurting my relationship with my husband ?
