Is "No Kids Ever" a Relationship Deal Breaker?

My guy friend A. is madly in love with a woman who has clearly stated that she doesn't want kids. Not ever. He's always pictured himself as a dad, but for whatever reason, she has decided that parenthood is not for her. This wasn't always the case. She was never dead set on being a mom, but she wasn't ruling it out. Now it's not even up for discussion.


I know that for many women, this relationship issue can be the ultimate deal breaker. I've been dreaming about being a mom all my life (although as I get older, I can see why certain people might not). Still, part of me feels sad that A. would give up having children for a woman, though it's not for me to say. Also, I wonder if and how it's different for men. Apparently it's not a deal breaker for this one guy. He said he'd rather spend his life with her than procreate and that he's happy to be the "cool uncle" to other people's kids. I'm not certain if he truly feels this way or if he's trying to convince himself otherwise, but I'm happy to support his decision to stay with her. I just hope he doesn't regret it.


What would you do if you were A.? Would it be a deal breaker for you if the guy you were dating didn't want kids? What about if he first said he wasn't sure and then told you he was against it?
