I know what that ongoing anger towards the OW feels like, how you know it's wasted energy, yet it's hard to stop your emotions from taking you there. I found it helpful, whenever she came up, to invoke karma--I would wish her whatever she put into the world, tenfold.
I figured, if she became a better person, that could only improve the world. If she continued to seek out married men, be self-pitying, refuse to take any blame, be a drama queen, and refuse to work on herself ... then the best she'd end up with would be a trail of miserable relationships. The choice was hers whether I was offering her a blessing or a curse. Then, having invoked karma, I'd force my mind to leave that subject.
Take care of yourself and try to relieve that stress with as much pampering as you can manage this weekend!
