I know it's a difficult thing to be dumped but that's just what he did. I think the best thing to do is to keep some distance from him if he does not want to be with you, sorry to say. I have done the same thing in wanting to help someone who did not really want me and it ended up with me getting very hurt, just to caution you. When a person wants to be with someone they make it pretty clear and he is not doing that. I would try to get my mind off of him and go out and have a good time somewhere. Maybe go out with others. If he wants you in the future he will come to you to be sure. That's my opinion.
