you say "One will always question, "How someone with such a divine brain, could fail such a simple thing, love, that too multiple times?".
I don't think love is a simple thing! Furthermore, I think he loved with his whole life, it is just the flames went out. He was a free man who did not want to be tied or ruled. He had the courage to say no when he did not want to continue any more
I dont think love is that much of a difficult think. Almost all of us fall in love but only a few has got the brainpower like that of him
