Ignore signs, keep waiting, keep driving and you'll eventually reach a point of no-return.
Where you don't have enough fuel to go back, and you're in the middle of nowhere. It's hopeless. You're pissed at your fate, yet you know only fate can pull you out now. Time stops.
Everyone must have points of u-turn in relationships.
It's when the absolute non-negotiables are broken.
You can either turn around hoping to reach where you were all fine,
A reset point. (It will take time)
Or just keep driving, keep waiting for god knows what-> run out of fuel.
