Frankly, I'm surprised she's still sniffing after you. "What does it matter?" "Far away from you?" Are you kidding??.
Hot girl getting engaged has nothing, I repeat nothing to do with you! She met someone she liked, they dated, he proposes, yay for her. It isn't because she doesn't like you or has some weird freaky contempt for you. You aren't even in her frame of reference. She has this whole other life past you, as do the vast majority of the female population. They aren't just waiting around to be objects of your desire. They are out living their lives. "That ends that." Nothing started it! There was nothing to end!.
