She didn't stop loving you. She just decided to stop showing it, because no matter how much she tried you just wouldn't get it :( But sometimes you treated her so special which simple made her over-fall and misunderstood that you guys are likely to be more than a friend. You get her confused for many times. You such a nice, maybe that's her fault for falling into you for once until now. If it was a trick, a bet, a gamble or something, then you've succeed in that way. Congratulation, you won.
