I'm 18 and talking to a girl who's really good looking in my high school, but has a boyfriend. I want to just be her friend but I feel I need to hang out with her outside of school so I can get to know her better, she's been flaking me by making an excuse each time I ask her to hang out. should I just keep trying to get to know her with the little amount of time i have to talk to her in school? I feel like Ive lost my vibe with her by trying to get her to hang out with me too many times, and I feel like there's no way to fix it.
