And then the very best thing was his attempt at a response: "Oh, man, I'm getting misty." I had to ask W what that meant. And she said, "Crying". I was like "Why is he crying?" She said, "Being sarcastic". I said, "What? Wow. Well, he doesn't matter."
Actually, THEY are making fun of YOU here. She is telling you that she GETS his humor and it went right over your head. He is calling you a crybaby in a nutshell.
You will NEVER win her back with this type of childish nonsense. Mature, confident men don't act this way. You are telling both of them that you don't respect him for interfering in a marriage, and yet you are telling her that you DO respect her, even though she is doing the same thing. This is making YOU look weak. Weak men are NOT attractive to women.
The actual facts here point that she doesn't respect YOU. It is coming across like you will take anything disrespectful from her EXCEPT if this is a PA. ????... (So you will take this from her if it is only an EA? You will take this from her when she will go out with him and refuse to go out with you?
That is not wise.
Jon, this IS an affair. PA,EA, or whatever else you want to call it. You won't earn her respect back until you show her that you won't tolerate a PA an EA or any type of intimtate relationship with OM. End of story.
