retsam2,
When one spouse cheats, if the other forgives, then the cheating spouse has been “forgiven” under the law. The legal term for such forgiveness is “condonation.” Condonation is a defense to adultery, so yes, if you forgave her adultery, then any cause of action based on the previous adultery will likely be unsuccessful. Keep in mind though, that if she committed adultery again after she moved back in that her actions could “revive” the past adultery, and thus it could possibly be “used against her.” That’s the best answer I can give you without knowing more facts.
