I am glad to read the above, UL. Spite and vindictiveness are not a way to live a life, even though they feel mighty good in the heat of the moment

Edited to add: It takes two to tango. If you really want to cut off contact, then just do that. Strategically leaking info to people who will tell him is not cutting off contact. It is maintaining contact. Dropping the rope, becoming a black hole is cutting off contact. I hope this makes sense.
