Best way to get rid of it is like the story in the back of the AA Big Book. Pray for that SOB, keep doing it everyday for two weeks. Ask that he have everything that you would want for yourself. You don't even have to mean it. It does work, not sure how, but it does.
I remember when I first got sober and I found out that my wife was sleeping with her boss. I was totally lost. We seperated and later divorce but I remember praying for her all sorts of things, new car, happiness, joy, etc. One day she brought the kids over to see me and guess what! ? !
She drove up in a new car,. LOL
I had to start my two weeks of praying again, but I learned that sometimes you should watch out for what you pray for :rotfxko
