The only thing I wish I knew was how to tell “when the sitch changes enough to re-evaluate.” My guess would be when she comes back begging YOU to stay. So, you know, 1-2 years...right? Or Sia can you clarify?
I think the more likely scenario for the sitch changing enough to re-evalute is when you get sick enough of the limbo and the crap that she is pulling and YOU make the decision that you don't want this person in your life.
