He says he paid for sex with escorts and that's why she's left. I was gobsmacked.
He said this. To who as an audience?
In which case, as he seems to be admitting this, I would predict he's going along the lines of:
"My wife was awful behind closed doors. Berating me, belittling me. Wanted no intimacy. Argued with me every time we spoke.
I ended up turning to escorts to fill this emotional and physical void. She found out 6 weeks ago, and left. It was over months ago though."
Now, for all you know that could all be true. You don't know what happened behind closed doors. She could have been appalling. He could have been appalling. However, I suspect it's been sold to the new woman as poor him, neglected by his wife and having to turn to escorts. And she's rather tragically agreed what a poor thing he is.
The pair of them will look like a laughing stock. He's gone from marriage to escorts to be girlfriend in 5 weeks. She's the daft bugger who's jumped to "save" him. I don't know who looks more ridiculous. And that's exactly how everyone will be viewing them.
