He was your "person"? To do what to? Abuse and mistreat?

Since you were abusive to your ex husband, you cheated multiple times and you got him fired, then he is 100% justified in not coming back to you.

It's time for you to take responsibility for any abuse that you have inflicted on loved ones or partners, take responsibility for your abusive behaviors, and get yourself professional help.

Please do not chase or pursue your ex. He has a right to a peaceful life without you. I have been abused in my marriage and I am divorcing said abuser, who refuses to own up to his abuse and get help. He also refuses to accept the ending of our relationship and a divorce. It's not fair to try and pursue your ex after what you've done to him. My ex is doing the same, and it absolutely enrages me. My ex is extremely toxic to me - and you are extremely toxic to your ex in your current state.

The best you can do for yourself at this point is to get some real help, including long-term therapy. Affairs and abuse do not need to be forgiven and sometimes in many people's minds are 100% unforgivable.
