Men during pregnancy

Hi, I'm 6 months pregnant FTM and just wondering could my man be affecting my happiness with this baby?

I've always wanted kids and when we found out we were pregnant we were overjoyed! My man has a 6 and 7 yr old already, both boys. Found out im having a girl! But there's something missing. I don't feel any connection between my man and our baby. I was excited and told him things about how shes growing and he seemed uninterested. Told him she can hear and feel, didn't respond So I stopped telling him. Now she's moving around and seems like he doesn't care. He doesn't try to feel her move, he doesn't talk to her or anything.

Is this normal? Is this just me? I'm not sure if I'm asking the right questions. I feel so alone with this whole thing.

Anything helps
