We've been living together for a year and a half. My DD is crazy about him. I am attracted to him, and I loved the way he used to love me. However, after five breakups, I think we have broken down. I'm not sure I remember how we got along before. We are raw and oversensitive and grudgy to each other after each "honeymoon" period. How can I break off from someone we love so much, when he and I have simply broken it? How do I stay strong enough to stay broken up?
