I think she will show some type of disrespect toward you, again. It may come in a different form, but it will happen b/c it's the nature of a WW.
You have told her you will not tolerate disrespect. Be sure you read the thread about the subject of boundaries.......what it means and how it works. You will need to have some type of action based response to her show of disrespect. That means you can't depend on words. Words don't work. Only you can do the action. Your action is to protect your feelings, and to be a consequences for her disrespect.
Your action is never to be an act of physical or verbal aggression. Your temptation will be to explain why you are doing whatever you do.........however, if you start, it kills the effect and opens the door for argument. Enforcing a boundary is not a time to argue.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
