Was I in the wrong acting as I did?

I recently broke up a couple. I had a massive crush on my co-worker and her boyfriend was this very angry and insecure guy. He felt so threatened by another man's presence around his girl he held a teen against the wall just for opening a door for her. He left my current workplace when he started screaming at our managers and a few co-workers. The guy has a serious anger issue and when he went on his screaming rampage I found her in a bathroom stall crying. He had left the establishment already and I comforted her. I started being flirty with her after the incident and we sort of just clicked. I told her we could not date unless she broke up with him because I don't accept cheating. Am I in the wrong or should I have helped this relationship. She told me she has felt like her relationship with him was ending a long time ago. So am I a bad person?
