Just another family-without-children woman checking in with my two cents. (By the way, it bugs me the way the word family has been taken over to mean "with kids"--aren't dh and I a family??? )

Anyway, DH and I decided in our early thirties (well, mid-thirties for him) that we did not want to be parents, and mostly we've never looked back. I say "mostly" because he seemed to experience a moment or two of regret (though, oddly, I didn't) a few years ago when I started going through menopause. But it was gone in the wink of an eye. Though it does suggest that you want to try to be pretty sure about your decision.

Like Emily, we're not very kid-oriented, though don't generally dislike children--as some people will think you do if you don't have any. But we aspire to be the best aunt and uncle ever, and have always had dogs. And maybe it's a little different because we've both been teachers, and have had an opportunity to do some nurturing in that sense.

Seems like I've heard there are support groups for the fertility-challenged. You might search the internet. On the other hand, know that life can be fun and happy and marvelously fulfilling, even without having children.
