Kim is right GM, let it out. Don't be ashamed to hold your head up high, you did nothing wrong. Let them talk, like Kim said, they will move on to someone else soon. People do get entertained in gossip especially in a small town. I also live in a small town and my xh was the Fire Chief of our biggest department AND a Police Sgt. for our city. EVERYWHERE I went people were consoling me, asking me what happened. I repeated myself a million times over. I didn't let it stop me from going out though. After awhile I just smiled and said Yep he is having a crisis I guess and changed the subject. He is the one that looks awful for leaving his family and not trying to save your marriage. After being together for so many years I will never understand why or how someone can walk away so easily without even thinking.
I read something on the alt. Do you have a alt account? Anyway, it said an elderly couple was asked how they stayed married for 65 years. They replied...."We come from a time that you fix what is broken iinstead of just throwing it out" SO TRUE and THIS is how it should be always.
