How can send him the right messages...?

WHen you message him, don't come off as you don't like him at all. A lot of times a boy will like her, and try to talk to her, but when they talk and the girl doesn't want to say anything because she's not sher how she feels, it comes off as you dont like him at all. Just talk to him like your just friends for now.. And when you figure everything out, then tell him how you feel.
