Okay, sounds like this married woman who did not respect her husband, you expected her to respect you?

If you do not want to be married, you leave the relationship, you get a divorce, then you carry on.

This woman had an affair with you and with her boss and with who knows who; that is not about you, that is about her and who she is.

"I had always figured she would choose me because I am a good person." Why do you want to be chosen by someone who does not respect or value any man she has been with that you know about? It sounds like she is not into "good" men, but into into "using" men.
