I agree with everything Anotherstander has said above. Stay dim. Use your limited interaction to show her that you aren't just surviving, you are doing just fine. Maybe even better than ever.
You can't shake the fog intentional and have it stick. But you can do things for your own mental well being that might just shake thing up a bit. Don't expect anything and you won't be disappointed. Much of this is beyond your control.
That said you can handle your end in the best way possible. BTW, we all slip or screw up. Just move on and don't do it again. Do not pursue her through her parents.
