I agree with everyone else, just let it go. It will drive you crazy. (My ex and I broke up on bad terms). After my divorce, my ex and I didn't speak for about a year and a half. After a while we were coridal to each other because of our daughter. Now we are good friends. I can call him anytime if I need him to watch our daugter outside of his court appointed visitations. He has even invited me over for a friendly dinner and a movie a couple of times. I believe that over time anyone can get thru and overcome a divorce.
