I know that it is hard to go dark. It was almost impossible for me. Looking back, I wish I would asked myself which is harder: going dark and possibly having a chance at a R OR continuing to pester her and end all chances of getting back together. I chose door #2. I hope you choose wiser than me.
FTR I have been dim/dark/no contact for 3 1/2 years. It does not guarantee anything but hope is with in us. As long as you have HOPE with no expectations, no one can take that away. This takes more TIME than most LBS's are willing to give. Make the best use of it because TIME is not something to waste.
Make your changes for YOU not to win back your SPOUSE!
