You dont say if the person wishes to forgive the wife? that is the first thing. It is difficult to forgive someone, especially fi they dont ask for forgiveness. I am sorry but I dont agree with the above poster. We are required to forgive people even if they dont ask for it or dont want it. Forgiveness is as much about our salvation as the other persons. We should forgive people even if they dont know they have hurt us and wouldn’t care if they did know, and even if they would hurt us again if they could. This is forgiving our enemies. We however, don’t have to put ourselves out there to be hurt again once we have forgiven the person. This is perhaps what the poster before me means. The first step to forgiveness is to ask God to help us. We just need to want to forgive and we need to give our hurt to God. Forgiveness is a difficult thing cos we are broken ourselves and we are hurting, we give your hurt to God to keep for us and to help us deal with it. We cannot do it on our own and shouldn’t try to. God wants to help us. Forgiveness may have to be done many many times over. It may be the person forgave his wife, then the hurt came back and he has to do it again. The wife has been forgiven, but the ‘affair’ has not been forgotten. It has been forgiven but not forgotten. So because we are too broken to forget it, we must keep on and one forgiving again and again. Does this make sense? God who is perfect hears us confess our sins and knows we are sorry so he forgives and forgets our sins. So he never has to forgive us again cos he has forgotten them. How wonderful is that!!! But we are not perfect , we cant forget so we must keep on and on forgiving over and over again. So yes your sins are forgiven and forgotten by our most Merciful and wonderous God and in all likelihood you have forgiven you wife (if you are that person) at one point or another, but it is just that it keeps coming back and must be done again and again. With God’s grace one day you’ll forget. Ask for God’s help, ask for the grace to forget and the grace to forgive and the grace of patience in the mean time. And thank him for his mercy. Also I don’t know if it helps, but God knows how weak we are, when I pray the Our Father, I often add in my head when we get the part about forgiving others, ‘with your grace’ and in any case God knows we need his help. Ask for it, often. That’s my advice, call on God often. He is just waiting to be asked for help and he will help you. God bless you.
