If your spouse had an affair with a contractor/cleaning person would you let that person move in with you and you take another bedroom?

Actually happened to a friend of a friend. They had a contractor living with them while working on their house. He wound up involved with the wife. So the contractor moved into the master bedroom with the wife, and the f-of-a-f moved into the extra bedroom.

I never heard anymore since I didn't know the guy myself but I expect they are no longer in that living arrangement.
