OP - I understand what you're saying, but NC is not easy especially while still having younger children. I did do NC with him for a while, but have found it easier dealing with H by using a friendlier approach. This is also a 180 because there was very little communication or interaction (his choice) with H for quite a while before he left.
My gf's H was my H's best friend. H has only talked to him once since he left and that had to do with a buck contest at work. They work in the same place. If her H had wanted him to know I think he would have told him.
It's not in my job description anymore to keep him informed of this kind of thing. H's choice again.
