WHY?
You thought your intense feelings for her were a testament to your deep love, but now you realize that your obsession was merely a reflection of your own self-absorption. She was simply a conduit for your own happiness, a means to an end, rather than the true object of your affection. Your fixation was never truly about her, but about how she made you feel about yourself. You mistook your own ego's whispers for the whispers of the heart, and saw in her a mirror to your own desires, rather than a soul worthy of love. Your passion was a solo performance, with her as merely a prop on the stage of your own self-obsession.
