I think it appeals to me to contact OW H because it feels like I'm DOING something. I am so tired of him having all of the control and waiting until he feels like he's ready to take some sort of action. Am I the only one who thinks like this?
What control does he have 'all of'?
If you want 'control', file for divorce.
If you REALLY want control, stop giving a rats A$$ about what he is doing and cut him out of your life. Go dark. Screw him and his fantasy life.
I know that morally you see what he and OW are doing as vulgar. I have been through a similar situation. I will tell you that once you tell OW's H you will open a can of worms that will bring more hurt and emotion onto your shoulders.
Why? Because your H will resent you, he will be ostracized and he won't stop the affair regardless. What HE and OW are doing is BS but the bottom line is YOU. What will benefit YOU?
Opening this can of worms and a can of whoop A$$?
Or
Closing the door on him and it. Let go. You want to control, control your reactions. Withdraw from the game that is being played out in front of you. THEY are not worth it.
