By forgiving the one who hurt you, you can find the power to convince your spouse to give your marriage another chance.  You're begging and your pleading will have to stop.  This might seem counterproductive, but this behavior will not get you anywhere.  It will only convince them that a divorce is a good idea.  Who wants to be around someone who is behaving that way?

By forgiving the one who hurt you can make a huge impact on your behavior.  If you start acting more mature and behave in a more pleasant manner, it might surprise your spouse and help stop the divorce.  In a very calm way you can explain that you don't want a divorce and you want another chance to repair your marriage.  Just make it clear that you are hurt and sad but you have forgiven them and that you still want another chance.  The yelling and screaming that they saw in the past never did any good.  You might be surprised how your spouse reacts when they see the change in you behavior.

By forgiving the one who hurt you, you are showing a more mature side of yourself that your spouse may not have seen over the last several weeks.  You can now suggest marriage counseling to stop divorce.  Counseling has helped millions of couples to repair their relationships and to prevent divorce, and what a wonderful opportunity you have if you can convince your spouse to do the same.

By forgiving the one who hurt you, counseling will be a great benefit.  It's a wonderful opportunity to show your spouse that even though they have hurt you, you have forgiven them and to show them why they fell in love with you in the first place.  If you can show an honest effort that you want to deal with your problems during your counseling, it might be enough to convince your spouse to not only to stop the divorce temporarily, but permanently.

By forgiving the one who hurt you and you have succeeded to stop your divorce, you must remember that your spouse was about to divorce you and it would be easy enough for them to change their mind and file for divorce later.  Continued counseling to maintain a good relationship for the long term would be a good idea.  It's easier to stop divorce temporarily than to have a good relationship for the long term.
