Met a guy I really like a few weeks ago how do I keep my cool?

Oh why you asking? you know the drill dork. Act like you are the very hard to get sophisticated too good girl for a while, slowly work it in. make him wonder if he has your approval. just be relaxed, and if he turns out to be worth your time, then show him you like him with subtle hints. Don't over text him though, maybe every other day. I Can't stand when girls text me everyday. Good luck playa.
