You should tell her. If she is a real friend, even if they don't see u that way, she will still wanna be friends

Oh my god you’re literally in the same position from when I was in sixth grade… I had a huge crush on my best friend that I’d, at that time, literally known for two years, and thought she was cute that entire time, but didn’t come to terms with it until late late fifth grade. We were super close and I didn’t know if she was bi or lesbian or straight but I went for it and they rejected me and immediately started dating my other close friend… yeah that sucked

So if they reject you don’t take it so close like I did. That’s why I haven’t dated anyone yet, because I want to be completely sure they like me back. Trauma issues of me taking it so close to heart, the way she rejected me, and some other huge and personal horrible events made me get a little too close to me not being here today 😁

Sorry I yapped too much but my point is

Definitely go for it, just be prepared to repair your friendship if they reject you. Don’t take it too close or personally, and definitely learn some coping mechanisms sooner. If you need some more advice since you’re in the same position I was def reach out and I can tell you more

how does she act with you? and how did she act with you?

Sometimes I feel like she might like me back, but she may just be doing friendly things, she’s more quiet around me than she used to be, she keeps trying to guess my crush (every time she guesses herself I deny it), she acts different around me, but it might just be because I’m different from her other friends, and she has a few crushes, but she won’t tell me one of them

yeah that seems like it on the surface. but have you thought abount obsever bias?

Oh then you definitely should tell her bro. If she is guessing herself as ur crush and she won't tell u hers, she is probably into u
