My ex-boyfriend and I have been together for the past three years. We are the same age(23). Although we went through a lot of ups and downs in our relationship (because he was very lazy person), we had always pull ourselves through the hard times and look past our differences. During the three years that we have been together, I have always felt that I have exerted much more effort into the relationship than he did. He finally ended things with me four months ago, stating that he has lost feelings for me. Although he is my first love, he has never told me he loved me throughout the entire relationship. I told him I loved him after 6 months when he asked me. We have cut all ties since we broke up. What can I do to make him realize that he had made a mistake for breaking up with me?
