Nygal, I agree with annabel. The NC has to come from your W, not you. Or from both of you.
Coming just from you will show OW that you do not have W's support. And it will undermine how position even more if your W continues to contact OW in spite of you telling off OW.
You can call me Dory/ Grl.
As a wise fish once sang,"Just keep swimming!"
It's no use to go back to yesterday because I was a different person then.
