How does he know what you can and can't forgive? I understand that he has regrets and feels guilty, but that is no reason to toss away a 10 year marriage. It is time to give Retrouvaille a chance.

He needs to have some faith in humanity. It is only 2 days. But for more than 50% of the people there it is a two day miracle.
