i'm 19 and he's 21, we started dating around 6 months ago. feels like i've met my soulmate. we've discussed marriage many times, at the start as simply something fun to talk about. i've always made it clear that i never want to have children. but as we spent more time together both of us realised that we do want to get married sometime in the future and that it's quite serious for us. whenever i bring up kids he just says that we'll discuss it when the time is right (because he wants to have kids). but what's there to discuss? not wanting kids is non-negotiable for me. he has agreed to it for now (even tho he wants kids so much) but i think he's going to try to convince me in the future. and even if he doesn't, he's going to resent me for it. i have a feeling he already does.
what's going to happen? he says breaking up is not an option. i sometimes feel like a villain for this, but he was already aware of the fact that i didn't want kids before we got into a relationship.
TL;DR: bf wants kids but agreed to not having any because breaking up is not an option for us, is this going to work out for us?
