Most of the "experts" here are divorced. There was no divorce busting at all.
I think most relationships are cooked at BD. My partner and I are still together--she loves me and sees a long-term future--but the relationship we had was dead. Letting go allowed a new one to crystalize. Whether that new one will satisfy each of us enough to go the distance is an open question.
If you feel you're more an expert in a particular sitch, do share.
