Eyes and Lisa, I understand and recognize your fears. So the question I would have for both of you is, what would it then take for your WAS to regain your interest/trust after it was "too late" for you? You will have effectively become the WAS and your WAS will have transformed into the LBS. Perhaps by then you will have successfully let go and gone forward planning your future without them, perhaps even with someone else. You would have a taste of happiness again, something you haven't had in a while, and then here they come knocking on the door begging you to come back to them. Which would mean that you would have to give up the plans you made, the happiness you're experiencing, perhaps the person you were experiencing it with, so that you could try again with someone that broke your heart.
I believe LBS's can only answer this question when they've reached the point you have, of considering that someday YOU might not want to reconcile. If nothing else, I would hope that considering this question would give you some insight as to how your WAS's are feeling now. It's likely they reached a point some time back where they felt it was just "too late." Perhaps empathy for their perspective might help you with your interactions with them now.
