<human>: I gave her my heart and she stomped on it. I was really good friends with her, or so I thought. I became the best person I could ever be in front of her. I treated her like a gentlemen. Even the few times we got into minor arguments, I let her win even though i wasn't convinced the slightest bit. We were always seen together, always talked, always had fun talks, and I swear she liked me back to a certain extent. It's worth mentioning that she's an absolute social retard, and I vividly remember a guy friend warning me and saying people like her are unpredictable. I'm sorry but after everything I've seen from her, I, and my guy friends, clearly saw it. With that in mind, and after confirming with my guy friends that she liked me, or so she seemed, I finally got the courage to confess my feelings and ask her out. She didn't say anything back, not even a no. Instesd, she went home and unfriended me on Facebook. It's been two months and I thought I was kind of over her, but I'm not. I saw her on campus as our paths intersected at the library entrance and she saw me then she turned her gaze away and panickly maneuvered around me. And I got the all-too-familiar butterflies in my stomach when I saw her. And I can't stop comparing every girl I see with her. It's like I want to get over her, but deep down I really don't want to. My conscious mind wants to, but my unconscious mind is reluctant to let go. And I know she's not perfect and I know there's plenty of fish in the sea, but my unconscious mind wants that one fish and no other, and is willing to overlook and ignore all of her imperfections as if they don't exist.

Help me... This feeling is the worst.
