I know, it is infuriating. I've been through that with a guy who just absolutely can't feel strongly for it either way. When he met me, he assumed children were in his future one day but didn't actively long for them, apart from sometimes thinking he'll prove a point to his dad or something.

When he realized I was radically CF that was fine, but he never joined me with some huge sense of relief or enthusiasm.

He had a moment of crisis when he supposedly didn't really want kids but it finally dawned on him that because he loves me and doesn't want to ever be with someone else, this seriously isn't a future option, but the choice is made - no kids. Then he said he felt bad that I am just shutting that door for him, while at the same time not particularly wanting kids.

I said he has a choice, it just doesn't involve staying with me. In a few days he happily told me I am more important and he doesn't even really want kids so awesome! Well, I wasn't that thrilled and explained to him that this is a big thing for people and that he shouldn't fear losing me at this point but honestly examine what he alone wants for himself and his life. I tried to explain that for me this is something fundamental, and that I am sure if he was on the same page as me there would be some sense of enthusiasm about it. When he considered kids, what appealed to him, are there things he needs from that experience that he will miss?

No, he remained totally shallow on this issue and told me that he honestly just doesn't care and never thought about it, and his main concern is that we are together. It really bothered me to bring romance into this when I needed a rational focused reflection on the choice to have or not to have children, but he just doesn't seem to care.

We moved on from there and he is totally over the topic now, but I am careful at best. I don't know how this attitude is possible and for me this conversation and issue is far from closed. It's a real frustration dealing with these people.
