I need help 😫

I’m currently 27 weeks pregnant and I am feeling completely neglected by my husband. We used to have sex every other day and now I’m lucky if we have it once a week. When we do have sex it’s for maybe 3 minutes until my husband has finished, no thought in the world if I have (which he used to make sure I did). He never wants to show me any type of affection or compliment me which I just recently cried to him about so he’s starting to do it a little more but it’s only because I told him that I feel neglected. He knows I feel like our sex life is lacking and he just blames it on him being tired. I already feel so insecure with the changes my body is going through and my husband being like this is making it 10x worse. I find myself crying in the shower almost daily. I’m literally feeling so insecure that I’m getting angry over him following women on Instagram (which has never been a problem because I’ve always trusted him). I don’t know what to do or how to make him realize how much I really am struggling.. What would you do if you were in my shoes? How did you learn to love your growing body in pregnancy?
