Hi SD
I think the thing with divorce is that there are both practical and emotional aspects to be handled. Unfortunately I have seen it is very hard to predict what the emotional fallout can be.
For example my wife had an affair and left the
marital home to rent a place and to 'be me'. I thought she needed space and we could maybe reconcile. She then started a relationship with the guy she had the affair with, which emotionally upset me, and I was a bit of a mess for a time. I got over that, met someone new and started a great relationship. Now I get emotional responses from my wife about my new relationship, and when I try to talk to her on a practical level she denies the emotions.
I have found that time and avoidance are the best approaches. Avoidance being things to try and hide the new relationship from her as much as possible so it doesn't result in emotional acts from her. Time worked for me in coming to terms with her new relationship and getting my emotions under control.
I don't really think education helps much on the emotional side, educated people can be very emotional and get in a real emotional state about their divorce.
So you have a situation where you and your husband were able to handle your divorce on a practical level. That is great! You and your new partner committed adultery which would have had an emotional impact on his wife. She has not been able to control her emotions and is reacting emotionally, maybe seeking revenge and wanting to spoil his new life as she sees he has ruined her life.
Whether you behave in a private way or not is irrelevant. When my wife committed adultery she never flaunted it, but after 18 years of marriage and me loving her deeply it was very painful for me. It will be the same for your new partners wife until she can move on. My moving on came with me finding someone new, and starting a new relationship.
But emotions are funny things, and I did not think my new relationship would emotionally affect my wife as it seems to have done.
