She just broke my heart again!?

She said she met somebody and doesn't want to talk to me again. We have known each other for 9 years. We had a good relationship and lived together for most of the first 3 years. However, both our families strongly objected because of differences in culture & religion. I had my doubts too because of that & made my biggest mistake and broke it off. I messed up further by getting into a loveless marriage which quickly ended. After that I realized my mistakes and asked her to forgive me and get back together. She did get back with me and said she's forgiven me. She broke up with me in less than a year. She said she couldn't forget what I did. I later learned that she broke up with me because of a guy she was seeing when I was married. Then she started calling me again and said she wanted to be friends and we started to hang out. Eventually we started acting like we were dating, including . I spent the last 3 years in this on again off again relationship. She ruined my life.
