The idea to dance in circles, I have stolen from others here.
If you must meet them, don't provide the rope to hang yourself.
If they have two witnesses to something and want to DF you, then
they don't need your confirmation and will proceed. But in all
likelihood, they don't have that and they need a confession to
get where they want to go- either your complete obedience and
throwing yourself at their mercy or kicking you out.
I agree that not meeting is the best option, but meeting to "listen"
is the alternative that shows the parents that you were trying to
cooperate. Keeping your life to yourself, if they needed a
confession, the likelihood that they would DF is slim (but not
out of the question).
