feeling insecure

I'm almost 7 weeks postpartum and now my husband won't show me any affection. He did after I stopped bleeding for about a week or two. But now he won't touch me or even kiss me. I'm completely healed and back on birth control and want to be intimate with my husband and he acts like he has no interest in it. He gets mad when I try to sleep with him or even when I try to kiss him. 😞
