Oh, and just to clarify what I said about players acting into you and nice guys not acting into you and it not really being about how much they like you... what I meant was, girls tend to think that a guy who asks you out six times really wants to take you out. It's romantic, he's swept away, it's flattering... but really, in some cases, it's a guy who doesn't feel rejected because he doesn't care at all. He'll ask you out 18 times if it's that what it takes to get laid. And not give it a second thought because he's doing the same thing to multiple girls.
As for the shy guys, usually they will be incredibly sneaky about their obseession. You will see them here, there, everywhere. They will casually mention that they happen to have bought your favorite chocolate bar by accident, meaning to give it to a sister, but since they're not going home this weekend you can have it instead... (a friend of mine really pulled this elaborate of a scenario, pretty sad, huh). The tip off is how much attention they pay, not the longing looks or whatever cheesy gimmicks that players will use. If a guy notices little things about you that not very many people pick up on, he probably likes you and is too shy to say so.
Ok, I think I have written a book now. Dating is hard y'all, but it's so much more fun this year than it was last year when I had NOOOOO clue.
