Something that normally makes me chase a girl is when she acts like she doesn’t care that much about me. I know that this sounds bad but there is just something about it that makes me want to work harder to be with her. Maybe you should stop being so responsive to him. Maybe you should stop making yourself so available to him, if that is what you do. You may have to start acting a little cold towards him to get it through to him that you are not going to keep sticking around for his antics.
