I recently started talking to this kid and we've hung out a few times and hooked up. I don't know how to tell if he's into me or not. He did say I'm a really chill girl and he wants to see me again. But the thing is he's leaving for college in a month and I don't want to get too attached. How can I tell if he's into me? And if he is how do I have fun with him without getting too attached?
