Just a little snapshot for you. My W prior to discovery was about to go on a 2 week "business trip" with OM (when I was already deeply suspicious). I drew the line that I was not happy about it but could not control what she was doing and could not prove she was lying. She then threw a fit and offered not to go since "if we get D, you'll use this against me. I would rather not go and leave with my head high when we D". Oh, and that she was going on a LONG trip by herself "to find herself" anyway.
Yeah right. She probably even believed that herself, but let's get real here. If you are going to monitor your W, it's best to be prepared for the worst.
