I think all WAS are manipulated to an extent by the OW/M, even if it's something as simple as being told ILY - these things keep them in the relationship. I expect most do a lot worse.

We can't do anything about it though. If you tell someone they're being manipulated they will deny it completely, until they are able to come to this conclusion by themselves.

You cannot teach a man anything; you can only help him discover it in himself.
