Last weekend, I got up the nerve to ask my crush out to lunch. He said that he'd like to, but was "swamped with work" and said maybe this coming weekend instead. Neither of us has mentioned this all week, and now I'm wondering, should I say something? Part of the problem is that I'm not sure if he's interested, and so I'm inclined to wait and see if he remembers (which would indicate to me that I'm on his mind). I don't want to seem desperate. What should I do???
