I can't keep on doing this anymore....

I've known my "best friend" since before we were 2. We've been through EVERYTHING together. You'd think a "best friend" who's always been there would be "caring". Well think again. My so called "best friend" has been treating me like dirt for years. Ignoring me around her other friends. Calling me names. Hitting, elbowing, kicking, slapping, and other kinds of things to me. Just when I think it's getting better, it gets TONS worse. A couple days ago I was at her house decorating cookies with her and her mom. She says something to her mom, and I tell her I thought it was rude. Her mom says that that's just her (tho if anyone knows her, it's probably me). Some things are said that I honestly don't remember, and then I mutter under my breath "God save your soul". Then, my "best friend" practically blows up and starts crying a lot. Her dad takes her into another room to find out what's wrong and to get her to calm down. She basically says that we were attacking her (verbally of course) and saying (in her words) "like I'm not mature or something" (tho she's really not mature at all). This is why I'm afraid to tell her things that would really help her. Sure, now it's a small meltdown, but if we can't tell her these things I could easily see it turning into violence and threats. I'm really scared cuz her parents know she's not doing well, but compared to what I know, they're only seeing the tip of the ice berg! This started in probably 2nd or 3rd grade, but from 5th grade on, it's been terrible. She claims to be a Christian, but her face lit up when she thought I said "g*d" (I didn't tho!) cuz she secretly loves cussing (she used to say the f-word like crazy but I somehow got her to stop)! I don't know what to do anymore! She lies, she steals, she hurts, she [acts like she] hates me! I would tell her parents, but I know I would be in for even MORE mistreatment from my "best friend"! I'm overwhelmed and completely in over my head! I can't just ditch her, but I can't keep on doing this anymore! HELP!

Scared
Hurt (mostly emotionally)

Maybe telling her parents is the right thing to do. Or even just telling your parents what's been going on.

Yeah, I've been thinking about that, but I don't what to say and my "best friend" would totally retaliate and hate me even more. I might just do that anyway, but idk, still not sure....thanks for the advice tho Nat *hugs*

*hugs back* If she gets help, maybe she'll become a better person and trust me, one day she will thank you.
