Friend told me this evening her husband of over 20 years had a one night stand. My first instinct is to say leave but the repercussions of this would be great. Both staying or leaving have huge ramifications. What would you do? Especially interested to hear the views of those who have personally experienced this, whether the adulterer or partner. Why? Did you stay? Did you leave? I want to help my friend and I've listened intently but I can't shift the deep seated feeling that trust has been fundamentally broken and can this ever be healed?
