AS, very good advice. I had the opportunity to discuss with W that contact with OM and not informing him to NC and not blocking was hurtful even though she claimed she didn't want to hurt me. She acknowledged that she was sorry and we left it there. It removed the tension and was a good conversation that if she wants to purse a relationship with me that this was necessary.
We'll see but appreciate your take. It was the perfect approach.
You're welcome! And well-done, I know it's not always easy to follow pointers given here, sometimes I wish I was better at following my own advice
