My wife cam to me a few weeks ago and told me she had been having an affair for the past 8 months. We have been married now for 11 years and have had our ups and downs but this took me completely by surprise. She told me she had stopped seeing this guy a few days before she tole me. She said the guilt was eating at her and she had to tell me. Now all the trust I had built up for her is gone. What should I do?
