Friend zoned me 3 times but then gets jealous of what?

Friendzoned101
Ok so too start off this girl friend zones me once but I cared for her still so I was willing to stay friend zoned and was starting to get over her. She then proceeds to go to the dance with me and we slow dance have a good time and what ever. And she texts her friend that she has zero interest in me. Like damn lol ok so friend zoned twice. Fast forward to last night I had a bunch of people over I would play fight with her and what ever bc as said she’s made it clear I’m her guy best friend. But by the end of the night I decide I was going to make a move on this other girl and said friend zoner proceeds to leave the room and not talk to anyone. So after about 30 minutes to an hour of this I go and talk to her and sure enough she was jealous. She also then posts on her story later that night “don’t get your hopes up because things won’t happen how you want them to or expected them too”…. And now I just want to know what to do?
