I left an abusive marriage in 2018 and disclosed the abusive behaviour to a close friend of 10 years who had also become DH's friend. I cut all contact with DH but she continued to see him (which was hard, but I recognised that he had not done anything wrong to her).
I then discovered that DH was in a relationship with my friend's housemate. I had been updating my friend about the divorce/ my game plan, and she did not tell me she was in a compromised position.
When I told her I knew, she told me how hard it had been for her and that she didn't have any allegiances and wanted to be friends with both of us.
I then ended the friendship over email - nothing angry or aggressive, but explaining that I had to take a step back for my own well being and privacy as I continued to fight for a divorce. Other friends find my decision to do this bizarre and cruel - for me, it felt like what I had to do to keep my sanity. My friend told other joint friends how devastated she was at my decision.
I saw her today at a party but did not approach her. My now EX DH is still with her housemate and I don't think there's any more to be said.
I acknowledge that in the trauma of leaving an abusive marriage and getting a divorce, I may have acted in a way that seems unkind towards her.
Do you think I should apologise for the hurt I have caused?
AIBU in thinking I haven't been the one in the wrong here?
