im not sure if shes just fishing to see if i would respond,
Please understand - it is not about YOU.
She is emotionally triggered and in the past your very presence soothes that for her, so she is texting you - she doesn't want the same relationship you want, it is a need for her an emotional hole that she wants your presence to fill the void - not actually YOU.
What's wrong with responding since you already engaged with her? Honestly, say "no, we cannot work this out - it is time for each of us to move on with our lives in separate directions."
NO need to play games with her or send her mixed messages.
NC is a tool for you to detach - not something to pull back out when you get yourself into a bind and don't want to finish the conversation now that you are uncomfortable.
IF you are truly undecided as you indicate here:
im not at the point where i can say for sure ill never be with her again but i am sure ill never stuck in the same cycle i was.
it is time to move over to the undecided board.
Are you sure you are undecided and not simply in a bargaining phase of grief?
