First you should find out if he's involved with anyone. If so back off. If not then try to remember some of the things that made you two interested in each other in the first place and rekindle those. If that isn't feasible then think of new things going on now and invite him to doone of those acitivities. Now don't forget you have to evaluate why you miss him. Is it a comfort thing or a real affection. Comfort get a pillow until you find a man that fits your needs, affection, then work really hard to show him that the two of you would be great together.
