I met a girl in my school, and we started talking, and I realized I like her a lot. We hung out last saturday, and we we connected, and she told me I was one of her best friends. But in study hall yesterday, she didn't seem as interest in me as Saturday, or when we first met. there were a few other of her (guy) friends there, that she'd known longer. Should I ask her about this, or play it cool for now?
