Kinda annoying.

So I'm only 13 weeks but I'm starting to get ideas about my baby shower & I was talking with my BF about them and he goes "I don't wanna sound rude but I don't feel like talking about this" I think that's rude because I listen to everything he talks about and give my opinion even if I don't feel like it. I feel like he's trying to avoid that we really are having a baby and it's becoming more real. Idk why but this kinda annoyed me. Anyone else feel the same?
