I was never a good DBer. I give better advice than I practice. I don't even DB well now; my wife and I still do a lot of the same things we did before. But several things I do know: You have to be willing to let them go. You have to learn to be happy with yourself and not need a spouse to feel complete. You have to be able to accept that there are things beyond your control, such as what your spouse does.
And yes, I can come back to your thread.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
