Also what I am learning is that DBing is for yourself too. At least you will know in your heart that you did everything, tried everything to make it work and if it ends you can walk away with pride and dignity because you took the high road. That is how I feel about it. I think many people get to a place of peace (or that is the goal) that they are DBing and want to be with their spouse again but learn to GAL. Learning that life can and will go on and they can be happy and productive without spouse as sad as it may be.
Just my two cents.
This forum has offered me an amazing amount of support. If you still believe in your marriage - keep coming back!
