Heh, I hadn't thought about this through the gifted lens, but I went to an early college, and I had several relationships where I was 15 and 16 where we seriously contemplated marriage. (Couldn't have been that serious if it was "several" relationships, right? But looking back, it does seem odd that my 15-16 year old BOYfriends would be talking marriage? We just felt SO intensely at the time, even if things flamed out.) There was a lot of serious dating going on in that school in general. I got married when I was 18, and -- though it felt incredibly strange societally -- I felt like I'd seen enough of the dating scene to know what I wanted. (PS -- Still happily married 11.5 years later) On the other hand, several of my classmates from that college are still not married (of the handful I still keep in touch with), so who knows how things will play out.
Umm... no advice as to the 12/13 year old thing, though. Those three years make a big difference. (Though, looking back, again, giftedness what the issue there -- all my relationships where with fellow CTYers -- and, thus due to time constraints and the subsequent distances -- just couldn't have gotten serious even if we were so inclined.)
Don't know if this was remotely helpful to you, but it made me realize some things about myself...
