"I really learned a lot from you" -- is that really a line or can it maybe mean that being with you wasn't a waste of my time but it is time to move on? The question here is whether you would go into the relationship knowing its outcome. Would you have rather missed all the joys and the sorrows of a relationship because it would eventually end like all things do in one way or another? Maybe it's a way of saying I would do it if it were to do again, just because our paths are parting does not mean I regret a moment of my time spent with you. Sometimes the courage lies not in the staying, but in the parting. Just another perspective.
