In your experience when an Ex shacks up with the OW does it work long term?
In my case he didn't leave for her. I found out about the affair, split with my ex, the OW stayed with her then husband for a while. They've since split and her and my ex are now together.
I'm not asking from the POV that I want my ex back, i have absolutely zero interest in that. I had just initially assumed it wouldn't last but it's been a while now. The reason I care is that the OW is now part of my DS's life
