Many users here had 'crush' on someone else at some point. But they've never met them, seen them, or talked with them. They don't know who their 'crush' is like behind the screen. They've taken a liking to the online persona their 'crush' has created. Truth is, as time goes they realize they've just taken an interest to that person and want to better friends with them.
I'm not trying to invalidate your feelings in any way!! :) and I agree with the things you've said about JD. He's one of nicest people I've met here. But what I want to say is, KS crushes may happen. But these crushes are just for fun, it's a way of showing your liking to someone, that you want to get to know them better. But these crushes aren't serious, and most likely to not work out. Besides, Kidztalk is not a dating site lol. Like I said, just for fun :)
