I haven't, but my friend did. Her cheating husband persuaded her to take him back, then spent the next year still cheating and feathering his nest for the OW by cleaning out their bank accounts slowly. He even stopped paying their mortgage for the last 3 months and she had no idea, she thought everything was fine. One day he woke up and left for "work" and never came home, left her with the kids and a house about to be foreclosed on and very little money and moved in with his OW. She's still trying to get it all worked out in court but she's had a very hard time of it.
I'd never be able to take a cheater back. Once someone cheats they can hit the road as far as I'm concerned.
