No sex life

The last time my SO and I had sex with Sept 27. We had our baby October 11th and still haven’t had sex. I did leave to help visit my family one time for a little over two weeks but other than that he hasn’t tried anything.

I can’t even tell you the last time he kissed me. When I left I told him this is frustrating and I feel like I’m the issue. I told him I was going to leave if I continue to feel like we’re just roommates. I need affection!! He said I’m not the problem, and that I never initiate anything either. I been back for a week and still no sex. Yesterday, I literally walked around the house with just a shirt and panties on and I got his attention. When I bent over, he put his finger in me, but took it right out. A few minutes later while on the couch, I grabbed him by the balls and was attempting to start something but I had to feed the baby and he got up. Any other ladies have the same problem ?

Before I got pregnant, we were having sex 3-4 times a week.
