WHAT DOES THIS MEAN me and this girl have known each other for a while I’ve developed feelings but she doesn’t?

So we’ve known each other for a while to the point we call each other sis or bro playfully but at the same time she climbs on top of me and starts biting me hard and licking me she dates people I date people but somehow we’re always back together everyone ships us when we dismiss it I’m confused because I have feelings for her and I’m always there to talk and anytime something’s up she’s usually the one who talks to me first I just don’t get it like I really wanna be with her but I’m not sure if she wants to be with me because we always do stuff together I have not made any “moves” as a way to preserve our “relationship” and at the same time I came out as bi and she was the first person I told does this make me in the bro zone the back up for when she’s done trying or what and no we have not made any moves sexually
