I am the childless aunt. I'm in my late 40s, never desired children, so that won't change.

That said, I met my spouse in my early 30s. Was worth switching countries for and that was 13 years ago. We met playing the same silly text-based MMORPG some years ago. I have never been very social, but not being social doesn't mean that you won't meet people in non-traditional ways.
