There's this girl in my class that I really like, but I don't know if she likes me. I've complimented her several times with things like, "I like your hair," and, "Your eyes are out of this world." She took them well and showed lots of gratitude. I've also chatted with her several times as well. But every time I walk past her, she speeds up her walking speed. Also I try talking to her sometimes when shes with her friends, but she ignores me. I just don't really know what to think. What should I do about the situation?
