Wow, Puppy, that is a beautiful prayer. I think parts of that prayer have already been answered, and I think other answers are yet to come. For example, I believe that your children are old enough to understand what's going on and see the difference between right and wrong. I think they will appreciate all you did to fight for your marriage. So many men (and women) would be out the door the minute an affair was discovered, but you chose to fight for this woman, probably in part out of love, in part for your kid's sake, and in part in reverance to God. She's fully in His hands now and this might just be the thing she needs to have true repentance that will lead her to salvation. Just don't give up on praying for her. Remember, the Lord did not come to bring unity to families, but rather to separate the sheep from the goat. If unity happens to be the outcome of that, then praise God. If it's not, but rather that the true character of someone is revealed, then praise God again! I know this is all so difficult, and I pray that I will have the strength I need if ever I'm faced with the same outcome down the road. Let us all look on to our reward in heaven!
God bless,
