Boyfriend doesn’t seem interested in sex

My boyfriend who is also the father of my child doesn’t want to have sex with my anymore. We’ve maybe had sex once in the last five months. It didn’t bother me much when I was pregnant because he said he felt weird since his son was inside me so I respected that but now it’s been two months since I gave birth (granted six of those weeks I was healing) but he still hasn’t even tried. I’ve tried multiple times and he either starts laughing if I’m kissing his neck (which he loved before) or he’ll say the baby is awake when he actually isn’t. I don’t understand. I know it isn’t all about sex but I feel so disconnected and especially after having a baby I just want to feel like a woman again 😔
