why would he say that lol

So most days I will talk about my baby I'm still pregnant but near the end 😁 I talk about her if she moving or has hic ups or things I still need to buy just little things I have lol the big things needed and my partner told me the other day to 'shut up talking about her because I sound obsessed 🤔😳😂 ' oh wow I didn't know what to say because he was serious and I have this little person moving around and growing inside me and can't wait to meet her ☺️ it's obvious I want to talk about her, what is your opinion on why he would say that it's not a major deal but I'm just baffled 😕 as he said he wanted this baby 👶🏼 but that kinda showed me something different that maybe he's not interested in her anymore 😢
