Just saying......take it from someone who KNOWS!!! Let it go...let it go...let it GO. That's the only thing YOU can really do and have a valid say and action in. Whatever's gonna happen...is gonna happen...because that other person CHOOSES the circumstance for it to happen. Save the only person you really can save.....YOU. And when and if they make it out with their mind intact, they'll remember...who was REALLY the one that was the "true" friend. Either way, don't hold your breath...don't expend any more energy. Live YOUR life. Spend more energy on YOUR peace. Love from a distance. And stay clear of daggers that may come too close because of the madness that's just not yours to suffer. That mess is not your path or destiny to have. Destiny....ironic, isn't it how some words can come back full circle?
