In particular, I am interested in hearing about people’s real life experiences of dating or marrying someone where one half of the couple was a kid when you first met and the other was an adult. I’m not talking about pedophilia…I mean, for instance, a situation where an 18 or 20 year old came to know an unrelated 6 year old (child of a friend or something), watched them grow up and then dated them when they were grown up and perfectly legal.
I’ve always been interested by people’s reactions to this sort of relationship. I’ll say more about what I think/where I’m coming from if the topic doesn’t sink like a stone.

For whatever reason, once I turned 28, every woman I’ve dated has been 8-10 years younger than me. I haven’t set out to do this, mind you-- they tend to look older than they are, and I look younger I really am, so when we first start seeing each other, we assume we’re much closer in age. (33-about-to-turn-34 now, dating a woman who turned 25 a couple of days ago.) A few times, in discussion early in the dating process, we’ll realize that we’ve crossed paths earlier.
The weirdest was when one young lady remembered me as “the nice candy shop guy” from her childhood memories of going candy shopping with her grandparents when she was 5 and I was 15. (We dated when she was 18 and I was 28-- we initially had guessed each other’s ages as being 23/24.) I actually remembered her from then, too, and was really uncomfortable when she began excitedly telling her family that she was dating the candy store guy. The relationship was fine, otherwise, and we’re still close friends despite the romantic side sputtering to a halt.
A couple of others remember me from social or retail things, when I was 18-20 and they were 8-12 or so. Oddly enough, I’m usually the only one uncomfortable with the age discrepancy. Others, including their friends/family, will bring up things like “oh, she had such a crush on you when she was a little girl!” and then suggest that it’s time I reciprocate that crush. Kinda weird.
Those that I didn’t know will still bring up odd things that make me feel creepy; they like bringing up things like “gee, I was only 8 when you started your current job!” or, a couple of years ago when my first cat was still alive, “funny, your cat is older than me!”
