Hi Mahhhty, I just caught up on your situation. Mine moved at lightening speed, but we're at about roughly the same place now: Disillusioned with X and dropping the rope. The LAST place I wanted to be when I first arrived here, but the best place for me to be at present.
I would love to write my H a letter. One that expresses all my regrets and sorrows, things I wish I'd done differently, how I could do better...oh, wait! I DID! I made the mistake of e-mailing it to him, and he forwarded it to OW for advice. The betrayal still aches. I find it ironic that his sharing my letter actually hurts me so much more than his cheating.
I'm determined to work on me. Heal. Be the best I can be. The best revenge is to live well, right? Seriously, I'm on the journey of a lifetime towards something greater. I know you are, too.
I'll keep checking in to see how you're doing on your journey.
