Well, I’m sorry it ended, but it seems long in the long term it ended for the right reasons (incompatible goals about children) and not for the wrong ones (idiot busybodies trying to undermine your relationship). Our society has a lot of criticism of age-disparate relationships, particularly when the younger partner is in their late teens or early twenties, and I have no doubt that it dissuades a lot of people from entering these sorts of relationships, and causes them to be less stable. In my view, such people (some of whom are on display in this thread) are not really any different from those who would criticize interracial relationships, same-sex relationships, etc., and as FriarTed notes it’s pretty amusing that some of the same people who would indignantly defend same-sex partnerships, etc., are so critical of age-disparate ones.
Anyway, hope both of you are doing well, and I’m glad you can still see each other now and again.
The kids thing is really important to get out of the way early on, for me anyway. A lot of people just assume that the person they fall in love with is going to feel the same way they do about having kids or not having kids. For gay guys, it’s even more complicated of course, but there are tons of childfree straight folks out there too who still want to fall in love and get married with someone else who doesn’t ever want to have kids.
So it’s a bummer that the relationship didn’t last Forever and Ever, but it didn’t have anything to do with the age gap… it was just because neither one of them ever brought up the kids question early on. And as the OP said, it was some of the happiest times of his life, and that’s great in and of itself. If she had been on the same page as he was (or vice versa), they might still be together today.
