what's her phone number? are you going to make me call her and tell her for you? like little jr. high kids? seriously dude, the longer you wait, the harder it gets. you just gotta suck it up and do it! not at the last second before you leave.. because.. what if she did like you back? then you two find out you're made for each other.. then you gotta leave like 2 seconds later.. it would be pointless. tell her asap. the next time you see her. even if that means calling her tomorrow to go to lunch with you, then tell her there. (I recommend telling her in person, and not over the phone, and definately not in e-mail) just go for it dude.
