This guy and I have been friends for years but we drifted apart when we were in middle school and now we reunited in high school. I've had feelings for him for so long but never acted upon them because we don't talk. At all. But in the summer of freshman year someone told him I liked him and he asked on if my friends and she said she didn't know and he said he only sees me as his sister. Ever since I rejected my feelings and dated a couple times. But he doesn't even look at me or say hi, he waves at my friends and he'll only say hi if I'm with them. He even says hi to my Mom who adores him. It sucks now that I'm a senior and I still like him. I know I don't have a chance. What do I do?
