If cheating somehow inadvertently kick-starts the "I'm not happy" discussion, and forgiveness and reconciliation follows, isn't it a mistake to think that everyone who cheats should leave the relationship? Some people go through a patch like that, both sides understand that it was stupid and a mistake and move on with their relationship.

Edit... kind of what Dezzy said. Soz... I didn't read yours till I posted this.
