Yup. In my experience, the OW has the only influence over the spouse. And it is with very selfish intentions. And the spouse is like a puppet, yet a master manipulator, too. They control each other in a sick way. Very unhealthy.

I think maybe that's why they don't listen to anyone else. Because they are so involved in toxicity that they want nothing to do with reality.

It's very painful and disturbing to see.
