Anyone else’s bf act totally uninterested in your pregnancy?

Did anyone else’s bf act super uninterested in your pregnancy? Is that a normal “guy” thing? I’m pregnant with a girl and I have multiple pregnancy tracking apps and like to keep up with baby’s size and new developments each week etc. I think it’s fascinating and don’t really have any friends or anything besides my bf so I try to talk to him about it or tell him cool “milestones” in my pregnancy each week but he’s completely uninterested. Like if someone were to ask him how far along I was, he literally wouldn’t even know. For example earlier I was on one of my apps and seen a little “fun fact” that said baby’s heart can start racing if mine is racing and that she’s growing finger nails this week. I told him about it and he literally just sat there, didn’t say anything I think he actually ignored me maybe. I just sat there because I felt awkward and said “don’t care?” And he blankly said “what do you want me to say?” I said “idk, maybe “that’s cool” or something, I’d rather you say something than nothing” and he again didn’t say anything and just ignored me. He does this all the time and it honestly hurts my feelings that he’s not as interested as I am. This is also our first girl which I’m extra excited about because I’ve always wanted a girl and thought he did too but he’s just very nonchalant about the entire thing. Even when we go to the store sometimes I’ll go to the baby girl stuff and want to just look around and maybe buy a couple things but he always says no and to “come on” like he doesn’t want to baby shop or anything. The other day I threw a $3 pink baby blanket in the buggy when he wasn’t looking and when we got to check out he picked it up and said “what’s this?” And I said it’s a cute blanket I want to get something for the baby since we’ve not bought ANYTHING yet and he just acted like he didn’t even want to get it. He’s not even told any of his friends we’re having another baby. He NEVER mentions the baby in conversation, me being pregnant, he never is excited to go to ultrasound appointments like I am, nothing. Sometimes I forget I’m even pregnant because it just never gets spoke about or anything. We’re both in our 20s and this isn’t our first child together, but is this normal? Was anyone else’s boyfriend like this and if so were they like this the whole time or did they ever eventually come around? He’s been like this during all my pregnancies and it would just be nice to feel like he’s as excited as I am or likes keeping up with it as much as I do for once idk. Maybe that’s too much to ask for🫠
