I would take today to make sure her BH knows. That would make me feel better to make sure that he knew. It would be sort of my revenge to WH and OW for what they did and her BH has a right to know everything you do. If he already knows then he might know more than you do. Absolutely make sure that he knows. Waywards lie to protect themselves in so many ways, when really all they are doing is adding insult to injury. (((HUGS)))
I hope your husband is in the closet strung up by his.....feet.
I am sorry, the pain sucks...but you are with a great bunch of folks who care.
