Sounds like you're ready to detach from her and the situation. I hope you find a healthy and positive way of doing it. Let every step you take be a step forward.
For me, "letting go" also meant letting go of the anger. Hopefully one day soon you'll stop speaking about how your W is disrespecting you or how your W is affecting you negatively. I found that when I started to feel sorry for what my W is going through and actually pitying her, I knew that I was in control...of me.
Compassion breeds strength.
