No Sex since Baby 😫

I'm going on 5 months PP and my husband shows no interest in being intimate with me. When I bring it up he will say "you're always tired" or "you go to sleep." I typically go to sleep after putting the baby to bed bc he is downstairs and we sit in my bed to feed her until she goes in her crib, which makes me sleepy. When he is up here I stay away to talk and stuff. Any advice. I will say that I am still healing and still having to go back and forth to the GYN due to a tear they didn't see and stitch (although I kept saying it and telling them I was in paint!) But he shows no interest.
Any ideas on what it could be or what I could do to fix it? I often cry. I'm already struggling with adjusting to my "new" body and it's very hurtful not to feel wanted. 😞
