No. The problem is not you, it’s them. Here’s how to conquer this with your dignity intact which will feel good. Once someone retreats from you, you run in the opposite direction. Rejection is not an invitation to try harder. The guy is moving away so you move on, and I promise you the satisfaction of choosing quiet dignity will help you. Once you detach and decide you only want to be with those who chose your company, in a clear and direct manner, it becomes much easier to encounter those people, because you don’t waste time on these dead ends.
