I found "Not Just Friends" by Glass particularily helpful. "Surviving an Affair" by Harley is also very good.
Not Just Friends explains very clearly what you're dealing with.
If she was sure she wanted a D 2 months ago and now just wants a legal separation, she's having second thoughts.
Don't worry too much about the "no future" comment. Waywards all say that. It's part of the script.
Obviously I don't know for sure, but if she says "we're just friends" and he was her 'refuge' I would bet she's very involved EA wise and very possibly PA wise also.
Does she really love you underneath it all? At this point, it doesn't really matter because in her mind, she doesn't. And until she's been NC with OM (even if it's only an EA) for a good period of time, she won't feel anything for you.
You have to get in that mindset. That her reality right now is she doesn't love you and doesn't see any future for you. Can that change? Yes, but it'll take a lot of work and time, time, time.
