Darling, he doesn't care. He doesn't think about you at night, he doesn't see your face in a crowded room. He forgot the color of your eyes, even though he told you he had never seen something that beautiful. He doesn't talk about you and about how bad he misses you. He doesn't remember what it feels like to kiss your lips. Sweetheart, he doesn't care about you, and you chasing him, only makes his ego bigger and your pride smaller. He doesn't love you anymore. I'm so sorry.
Honestly. It's just a stupid crush. He hardly is even aware of your existence. Don't waste your time. He isn't wasting his thinking about you when there are so many other prettier, thinner, funnier, and happier girls around.
