It is the right thing to do. The only thing to do, really. Let them go, detach. Truly detach.
The end result that we want, of course, is a marriage that is better than it was before, where both partners are aware of what led to things getting so screwed up and know how to better cope with "life" and problems as they come.
For me, it is so terrifying to think that 15 years together means nothing to her and she can just throw it all away. It is all a fantasy of how much better and easier they will have it without us. Maybe the only chance we really have is to let them have a taste of life without us so they will know it really wasn't that bad. It's a huge leap of faith, but I guess we have to have faith that IF our good old spouse is in there somewhere, they will make the right decision for their family.
