If I may respectfully interject,
I understand the “Catholicness” of this problem and where the OP is very frustrated. I also can understand where the husband is coming from. We probably have the same mind about kids, although I’m female. The hard thing about this, as I’m sure everyone realizes, is that there is no compromising. The OP wants a major change in lifestyle and the husband is taking awhile to become ok with that idea. That does not mean he is evil or loves her any less. Just to play devil’s advocate here, put yourself in his shoes. He’s probably scared poo-less of the awesome responsibility that kids demand along with fear of the unknown of giving up life as he knows it. The OP may be ready, but BOTH have to be ready to accept parenthood, otherwise the situation post-baby becomes unfair to everyone involved, including baby. OP, instead of getting frustrated and mistrusting him, try to find out the core reason for his fear in a heart to heart discussion, either alone or with the help of a third party. As frivolous as they may seem to you, his thoughts and feelings are very very real to him. Maybe he’s trying to accept the idea but then gets cold feet. A baby is way too big a deal for you to just get angry at his fear. People can say all they want about how this could have been handled or how to get out of it via annulment, but I see that as useless discussion. The two of them are in this and in this together, and they need to try their hardest to work it out. I’m not saying that the OP’s concerns shouldn’t be listened to and discussed, they need to be! But too many times the person scared of having kids is dismissed as the selfish, controlling one when there are, most of the time, serious issues to be dealt with on their side as well.
I’m terrified of babies and pregnancy and with the possibility of engagement, could be facing the same situation. Instead of Catholics ganging up on me and telling me how evil and selfish I am all the time, I think it would be alot more helpful for people to try and understand my fear and help me handle that.
OP, maybe spend time volunteering with babies and children so he knows what makes them tick and develops confidence with them, since you stated he hasn’t had much experience being around them. Beware, it might take him a while to warm up to that! Or let him vent and lend an ear to him without judgment, then talk about ways to address those issues that make sense to him. Don’t give up on him OP, I hope no one gives up on me either!
I wish you both well.
