Wow, twelve years olds dating? What has the world come to. By the way, this should go in the dating section.
"Dating" and actually dating are two completely different things. When middle-schoolers say that they're "going out" with someone, "dating" someone, etc. they just mean that they're sort-of-together with that person, and often it basically just means they're ACTING like they're together with someone. (Trust me, I'm in 8th grade.)
Anyway, as much as I really don't recommend asking someone "out" in a text chat, if you really think it's going to work, then go for it.
