Ugh 🥺 Anyone else experience this?

So I got my BFP today, and after months and months of trying my husbands reaction was so monotone and not seeming excited at all. He swears he is, but he’s just not showing it and isnt even interested in talking about it at all. Maybe the first doctor appt or hearing the heartbeat will change his demeanor? We’ve both been so dedicated to TTC and its like we finally reached the goal and hes so blah about it. Is this a guy thing? Idk. 🥺. And I’m sorry if this isnt in the correct group I didnt know where to post.
