Anyone else?

Does anyone else on here have intimate problems with their SO after the birth of your child? My fiancee won't even touch me. And I feel like I'm not what he wants me to be. He will watch porn, add scandalous women on his social media accounts, but he will not be physical with me at all. I'm begining to become increasingly frustrated both physically and emotionally. I want to leave him because of it. Is that shallow for me?
