Don't sit around waiting and hoping and hoping and waiting, girl. Ask to meet with him face-to-face and tell him the truth, the whole truth, about how you felt before and how you feel now and that you don't just want to be "friends" and see what comes of it. If a real relationship can't be worked out, then at least you tried and you will be respected by yourself (and probably him) for being very brave and honest. Life's too short to wonder if you will ever get what you want from this guy "in the future."
