lodo, you do have to pick your battles and if you know you can't win then it doesn't make sense to engage does it? If no contact with om is one you cannot win due to work situation then you're right, don't even try to enforce it. It's like that with my H and ow, business that turned into an affair. I am sure I will be labeled wishywashy or weak or whatever but I know that I cannot enforce a no contact ow rule so why would I even make it an issue? Pick your battles wisely.
