I need some advise!

My babe was born on the 10 of December last year and after his birth everything has changed between me and my husband. It's like I don't feel the way I felt before I became pregnant about him. It's been a struggle ever since just to open up to him. I'm not even in the mood for sex anymore. I will constantly push him away or find an excuse for why I'm not in the mood. It's like I'm over the relationship. The 'inlove' feeling is gone! I thought it was only the baby blues but it does not get any better! Any of you guys felt this way? Does it get better? 😢😔
