I like it a lot... I totally get what he means at the end... COMPLETELY. Basically, he had what he thought was a wonderful relationship with this girl. Eventually they broke up and he felt as though I guess, he finally realized the "routine" he was living with the original girl (she was taking advantage of his kindness and willingness to learn) and how amazing his new relationship is. He's resentful so he has the right to tell her off. Voila... my interpretation.
