I need help. Like this i've known this girl for like 5 years. We weren't close at all at first but two and a half years ago maybe I have felt something for her but I wasn't really sure of my emotinos so I just ignored them. We kept getting closer and closer. But 1 and a half year ago she texted me and said she liked me and a bit later we dated for a week or so, and I fell in love with her, but she didn't. Afterwards we were still friends and we still are. We see eachother twice/three times a week because of a school activity and during that time I really feel like she's flirting with me or likes me but at the same time I think the exact opposite. I'm still in love with her, I can't stop thinking about her and it's really affecting my grades, my social life, basically everything, I'm lost and I'm daydreaming all the time. I'm depressed and sad. I can't date other girls because I love her. I don't know what to do, I want to try something with her but I'm afraid that I might lose our friendship.
