A. This is a really complicated question, but I will try to answer in a short version. In my 40 years of practice with couples, I have found that cheating is NOT the greatest emotional trust issue in a relationship. LYING is a bigger trust issue. So when a person has evidence that a partner has cheated (not just suspicions), and can confront the partner with that evidence it is always better to answer with the truth than to lie. The relationship will have a much better chance of healing the wound of betrayal if both people agree to tell each other everything and make their lives an open book.
