Most Helpful Guy
Nothing. Why should he miss you? There's nothing to miss. You didn't give him any attention, you pushed him away and now YOU'RE the one missing him, don't try and turn it around and make it his problem.
If he doesn't answer your texts then there is nothing much you can do, he's already lost interest. Stop messaging him. There's a slight chance he'll come back and change his mind, but I wouldn't count on it.
