Like saffie, I was the last to know, and H only told me because OW's H said he would do it. H told me bare minimum (because he watched me visibly reacting to the shock), and then OW's H called me a week later and filled me in on more. I am so thankful to him, we still talk weekly, but not about them. We talk about surviving this.
You were so right in what you did. I applaud you, I really do.
