MissUnderstood,

Did he tell you why he took her home?  Would those be the same reasons on why he will cheat again? If so then how can he guarantee that he won’t do it again?

I remember a story of a wife who told her husband that the next time he cheated that he would have to give up his most prized possession.  This way he would think twice before considering doing it again.  I think it was his boat.  You might come to an agreement with that in mind.
