Maybe she's hung up on your spying more than the exposing. The idea of being able to break into her account and see her initimate and risky converstations.
Just like she hurt you, she feels hurt. She probably wants a lot of control over what is going on. She's probably doing a lot of self-talking herself into thinking she was right, justified, not bad, etc.
Aren't these the times you need to say if this is a woman you want kids with!
Let her pursue him. If you find ways to keep up the pressure to leave the FB people or have them leave her, great. But in the end, she may just hide her online attempts at an affair better in the future or go after a man at her job/etc. She seems a bit vindictive...out to punish you. Love makes people do all sorts of bad things.
Really though, you exposed her and she filed. She's got some real guts to not even apolgize. So let her go off like a wild cannon.
Go ahead with your life, your goals. Work on the 180s and moving on with your self-improvments. IN TIME, she may notice, turn back, and ask forgiveness. Maybe she won't, too. Do you want to look back in 6 months and say, "what happened to my life" or "wow, I can imagine being happy with her or without"?
