I think limbo is hard to actually see. To me, it's like somewhere stuck in the end of replay, where they have realized that the OW is not their "soulmate," their new life didn't fix them, they've stopped running from thing to thing, spending wildly and all that, but they're still not ready to look deep within or take the next steps so they're just kind of stuck living the life they currently have because they don't have the motivation to make any new changes.
It's not like deep replay, where they are like wild manic aliens, high on the euphoria of "freedom," spending tons of money, jumping from new thing to new thing. They haven't reached the real depression stage, because that brings on real deep dark depression. They may have settled on a new job, live with the OW, and by all appearances are living a "normal" day to day existence, but it's just because that's where they landed after the manic craziness of replay wound down and now they don't have the energy to move forward any further.
I don't know if that makes sense, but that's kind of my take on it.
The desire to be loved is the last illusion. Give it up and you shall be free. ~ Margaret Atwood
