Help me decode her "me too" behavior

My ex-wife was pretty bad at the “me too” thing. One of the big reasons she’s my ex now.

That said, I’m not saying it’s all on her there. Part of her “me too” behavior was because I was probably selfishly doing a lot of fun stuff and then grouched when she tried to do the same.

And why did you do that??

It’s the “with her history” part. And he mentioned her “history” in another post too. It’s obviously an issue to him. He could have just said she didn’t need to leave town to cheat, which of course is true regardless of her history. A woman can find someone new to bone in 30 seconds if she wants to, it doesn’t have to be one of the huge number of former sex partners she has in her sordid past that he’s big enough not to throw in her face.
