Ok the popular opinion is that contacting her will not help. It will cause her to turn to WH and have another thing to bond them together....you know she complains about you and is so stressed that you called her, etc. (just a guess)
Your H will be peeved(NOT THAT IT MATTERS!!!).
But here is something else to think about--it is a lot easier to not have to face what she is doing when she doesn't have to have contact from you! If you do try to contact her, don't expect what you say to make her leave.
If she was a friend of yours, I guess that could change the rules a bit.
