i have a friend who is younger than i, she has a group of friends, three of her friends a have stabbed her in the back and ganged up on her and every time they do she comes to me and i help her, then she ends up going back to them and never hangs out with me. also she will only talk to me if its about her boy troubles, now i don't mind helping but if i ever go to her with a problem she has short answers like "hmm" "idk" or "that sucks" and doesn't seem to care. she says im her best friend but she never asks to hang out, i feel like im friends with a two faced person, how can i tell if she's lying to me? because i've already caught her a few times but she's quite the little actress
