I was able to resist because I knew that being silent would bug him more than ANYTHING... and with that was the added benefit of keeping my blood pressure under control (especially after I stopped listening to his messages and deleted his emails before reading). In the end I realized that going no contact was by far the smartest thing I ever did to regain control of my life and my sanity. It also was the quickest path.
Besides, blasting him with words is like clanging a symbal.... it's just noise to him and gives him satisfaction to know he still has control.
Do Not Do It.
