Most Helpful Guy
Be more available... contact him or see him. Tell him how much you miss him. Tell him you've had time to think. See if u can give it another shot. Other good comments below too.
Guys are direct and literal. Remember you probably only have 1 shot at this so think about what he wants in a woman. Not how you think a woman should approach the guy. Put yourself in his shoes. How would he want to hear this? Then make a plan and go for it. Worst case scenario you are in the same boat you are in right now.
Have confidence in yourself but be prepared for rejection... if not u have something to offer to the right guy.
