I'm a girl and I'm bi and in love

I'm a teen girl and I am bi and I really like this girl in school, so much. There have been rumors that she is a lesbian but I'm not sure whether to believe them or not. I've never liked anyone like this before, I saw her hugging another one of her friends, and I'm so depressed now. Me and the girl I like never talk and we aren't in the same class, but we are in the same year and I don't think she likes me that much. We always have those awkward moments where we just stare at each other from a distance, and I want it to last forever, I, I just love her so much how can I deal with this? Bear in mind that we never speak to each other, just stare so I can't speak to her about it. I'll tell her one day

Start a conversation and ask her if the rumors are true. If she says yes, tell her u r bi. If she says no, say they r really mean for starting them. Make sure u r in private.
