I am a divorced woman without children. My ex and I broke up because he was attracted to other women and I wanted a strong commitment. He also didn't want to have children. After we got divorced, he was in a relationship for 4 years. He recently broke up with his girlfriend. Now he has been coming over and calling me. Recently we've started having sex again. We have a great sex life, but I am not interested in becoming his wife again -- unless he goes for a year of therapy to explore his inability to commit. I don't want to be hurt again, yet I enjoy having him in my life. And I am happy to be having regular sex again. What can I do to continue the relationship but keep him at a distance? I'm past childbearing age now, so having children is no longer an issue.
