Dealing with the reality of separation

[PeteWyo]

So here's a new question. I am still friends with the OMs ex fiancee, the one that broke up with the OM for my W. She is in not such a good place, she was supposed to be getting married a few weeks ago. I want to tell her about DB. I don't think she wants to save her R with him but it might help her do some 180s for her next R. Is she too close to this for me to tell her? I want to share and I have been giving her little DB pieces of advice. But I'm afraid she will come across my posts and somehow it will get back to OM and W. And judging on the things they think right now and they have said, he will only use it as ammunition as to why he is the answer, or whatever. Thoughts?
