As suspected she is keeping in touch with OM and they seem both to hold out hope of getting back together physically.
I am so sorry you found this out. But don't panic just yet. You seem very compassionate, and still love your W deeply, so I think if you wait it out a bit (with some patient nudging/reminders about her re-committing to the family), she'll be back intact soon enough. Take care! If only all of the DB women had H's like you, this site wouldn't even be necessary!
