Yep. You'll probably never know why. I'll share a paragraph of my farewell letter to my ex--which I burned instead of sending. Context: She refused to update her FB status to indicate we were a couple after 2.5yrs, and In the same week she told me we were forever, she told two acquaintances we were friends and an in-law who has the hots for her (but she definitely does not feel them back) that we were "broken up but talking". I caught her in a couple lies over that last one--
"I forgive you. I don’t know if you were ashamed of me, or were telling them fake news about me, or wanted to be flirted with, liked to silo your life, or didn’t want to share about us in case we failed. Your misleading side makes it hard to know. It was stressful trying to work it out when I was with you, but I’m not anymore. I let go. This says more about you than me. I hope you live a life in the future you’re proud of sharing with the world."
