Hi Kelly,
Give him space. Meaning don’t talk to him, sent him messages, anything, for a while. I know that it is really difficult when all your instincts tell you to do otherwise, but I think you’ll just be pushing him further away with all your efforts. You’ve already tried this anyway and it hasn’t worked so far, most people in this situation, when something doesn’t work, think that trying even harder is the answer, but that just creates more resistance.
Once he has space then if he wants to continue seeing you then he will, if he doesn’t he won’t, as harsh as that may sound. But you can’t force him to feel differently, and the more you try to make him move in a certain way the less he will want to go that way, it’s counter-productive, so that’s why I think the best thing to do right now is to give him space.
Ben.
