hey man...i understand that you don't wanna say anything to her again because you don't wanna feel like an idiot.. but how will you feel if she ended up liking you this whole time but never said anything & she just stopped liking you when you could've done something about it. running fast is most likely not gonna score you points ..but being nice to her & giving her compliments and just being sweet definitely will.just wait it out for a while & you still feels that she likes you..go for it!
