I know several couples who experienced adultery in their marriages, but because in each case there was a wife who was willing to pray and a husband open to allowing God to change and restore him, the marriages are still intact and successful today. Only prayer, a submitted heart, and the transforming power of the Holy Spirit can work those kinds of miracles.
