I am working overseas at the moment, doing a very stressful job that leaves me little time to do anything else. Because of that my OH stayed back home with our two children (3 & 6). About 2 months ago I found out that my OH had been kissing her best friend?s partner. We?d had problems before I left but I challenged her, forgave her and she promised it would stop. She made me promise not to tell the OM's partner. All seemed good when I came back home for a visit a month ago. She even told me that she thought it had strengthened out relationship. Now I have found out they were having chips and champagne together in the park almost as I was flying back. They say it is all over but I don?t know what else has happened between them. I am in two minds what to do. On the one hand I don?t want to lose our family but on the other I find that I can?t possibly trust her ever again. Should I tell the OM?s partner ? he?s lost nothing so far.
