If you are desperately trying to convince yourself that your spouse has not strayed, take this as a sign that something could be wrong. Trust your instincts, if they tell you something is amiss. Remember that cheating spouses can often be great liars. Furthermore, your spouses’ friends might be covering up for their infidelity so bear that in mind. Investigate for yourself, then confront your spouse calmly with the evidence that you have found, if any.
