In my situation I came to the point that I felt I had to distance for me and for her. Your H sounds like my W. Her and I have been best friends and she doesn't really have anyone else to confide in.
For me it just came to the point that it felt like she took our friendship for granted so I felt I needed to distance for my emotional health and for her to realize there are consequences to her actions.
Do I worry that it's going to push her further to the OM? Honestly I don't even think about what she's doing for the most part anymore. The only thing I really think about in regards to my W is that I hope she is safe.
If I were you, I would stay mum and upbeat. Focus on yourself. Listen to Jack. He gives great advice. Have you read the resources that they have on here?
