My Wife is having an affair

If your wife is having an affair, stand up and say it is wrong (Josh. 1:6). Ask her to stop. If she refuses, ask her to at least put it on hold. Be the leader and make an appointment with a counselor and ask her to go with you. If she refuses, you go alone. Even if she doesn’t you continue to do right.  I recommend Torn Asunder: Recovering from Extramarital Affairs by Dave Carder. 

1Peter 3:7say, “Husbands, in the same way be considerate as you live with your wives, and treat them with respect as the weaker partner and as heirs with you of the gracious gift of life, so that nothing will hinder your prayers.” (NIV)

You’re not alone. God promises to restore you. 1 Peter 5:6–10 “Humble yourselves, therefore, under God's mighty hand, that he may lift you up in due time. Cast all your anxiety on him because he cares for you. Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that your brothers throughout the world are undergoing the same kind of sufferings. And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong, firm and steadfast. (NIV)
