May get hungry again, but that hunger will be satisfied by another food. When they are done, they are done.
To me, this sounds like a jaded opinion of someone whose spouse chose a different food.
They might, they might not. Thats not in our control. What we can control is what we look like in case they show interest. Id say that there is plenty of empirical evidence that reconciliation is possible after a spouse is 'done'. Doesnt mean its likely; but I would say it's possible. Unfortunately you wont know if it will happen for YOU in your sitch until it actually happens.
