Maybe I’m asking to much

I had my baby three months ago and I have been feeling crazier than ever lately is this still baby blues? I thought it would be getting better by now. My SO has been having a hard time with his other daughter mother lately. And says me having feeling and acting cold and distant isn’t convenient for him right now. I understand that I want to be supportive of him and help him but I also need help from and some reassurance That I’m not just a tiny humans snack bitch and just there for him whenever he wants sex. I need some reassurance that I’m still beautiful and doing a good job and that he still loves me. Is that wrong? Is this just because I have issues I need to work on and not his problem. He says he’s just not that way romantically and he doesn’t know how to show he cares he bought me a car and that should be enough. but to me it’s not about buying me things it’s about the little things and I know he can do it because he used to in the beginning. I don’t want to change him I just want some reassurance he actually still loves me. I just don’t know what’s wrong with me I’m tired of being a lone and sad.
