disappointed on my husband lately

I'm so disappointed on my husband lately , he acts like  it's whatever to him when I say something about the baby , if I mentioned when his kicking me , or how many weeks I am he just looks at me , don't get me wrong his a great husband and loving towards me . He's always being to every single doctors appointment and it's happy about having a baby but There's times that it just seems like he could careless ! i can count all the times he talks to the baby , I'm not saying to do it everyday either but at least to act like he cares , for example we had an argument yesterday because I confronted him n asked him why he acted like that ? Everytime I brought up to have a gender reveal he just looks at me or a photoshoot he just stares and that's all he does n I hate it ! I feel like he doesn't love the baby 😔which I know he does , but idk it's hard to explain. He was a previous 9 yr old child with his BM and his not like that with his daughter , and it hurts me to see how his so different with ours ! he says he acts like that because back than when he used to rub my belly I used to give him an attitude and it's true I did but I have my reasons to it , n I feel like he does it so I won't complain but it's being a while from that I haven't complain since ever ! Like I said to me his more than loving Bt that's it just a "hey baby how are you doing in there going , we love you and blah blah " from time to time  , but his not like the other daddy's to be that are super excited ! And it obviously hurts me n gets me down ! Feel free to comment !
