Okay. Here's the story. There's this guy I've liked for a LONG time now, and I think he likes me too. Like, he's always polite and quiet and nice around me etc...just all these hints. Last night I asked him to go to a dance next week with me, and he started saying "i dunno" but not like "I dunno if you're good enough", just a normal. And I told him to tell me on monday, but hes the kind of guy to not say it. So how should I approach him?
