That's two-faced bullshit. She keeps you around for the attention and stability while talking shit behind your back to feel superior. It's exhausting and manipulative as hell. You don't owe her shit just because you've known her since elementary. That betrayal hurts, and it's normal to feel pissed off, hurt, and confused. You can't control what she does, but you can control how you respond. Set hard boundaries,stop sharing personal stuff, pull back on the time you give her. If she comes back lovebombing, tell her straight: "I need space right now or just fuck off.
