Have you had therapy? If you have a good time when you are together, what is this "more" you are looking for? Do you really have a relationship to end? See him when you want to, otherwise be busy when he calls. Is being involved with him stopping you from meeting someone more suitable? If you dont have a better choice, he doesnt become a better choice just by virtue of you stopping looking for other choices. Some men dont want to get married again because they dont want to divorce and lose half their worldly belongings again. Aside from the fact that its depressing.
