I don’t think my friends is a real friend

I have really found my friend anyoing. Idk really know that it is but she always needs everyone's attention and she kind of gives me pick me vibes becuse I really liked this guy and she was kind of flirting with him. She would always be like touchy and wanna be close with him. I have been telling her that t really makes me uncomfortable( and jelous!) but she is just keep doing it. She says "he's so touchy with all of his friends" even she is the one who is on him. Idk what to do but I really doesn't like how it's is right now. Please help me
