I agree with Dandy. I thought that it would be polite to respond to my ex's email a few months ago (when she purported to be making amends). Big mistake. The ensuing back and forth emails were pleasant enough, but I was annoyed by it all. She admitted to still using drugs and her words were nothing new. She tried to twist things and manipulate me. I resumed no contact and felt immediate peace. In the future, if she contacts me again, I simply won't respond because I'm not interested in having that delusion in my life. My life is far more peaceful without any engagement. Delete. Delete. Delete.
