Feeling a little alone

Anyone else’s boyfriends/SO not have any interest in buying stuff for the baby or getting prepared? He says he’s excited, and I guess it does seem like he’s excited. But he doesn’t want to help pay for ANYTHING. We both wanted a baby and now I feel like I’m the only one “in this”. I’m starting to get annoyed and frustrated that he doesn’t have any interest in getting prepared or even talking about it for that matter!!
