There are times that you feel sick about a decision you have to make.
And it's taken me forty years - and lots and lots of examples - to finally realize that is a good sign that it is the decision you HAVE to make.
Is there a last minute chance for this particular decision to be taken from me? Sure. But I am not hopeful.
(BTW, I am not talking about my romantic relationship here; though earlier romantic relationships were good examples of this)
