*sighs* i've went through this before too... its really upsetting and bleh.. tell your "friend" a lil piece of your mind! ARGH!! you dont deserve a friend like her. you deserve 1000000000 times better.

You should write something to let off steam ;)
As long as you boyfriend believes you, it doesn't matter.
Cheer up ! :)

Ignore her, she's just being mean to people who are above her, she's low that's why she wants to drag you down.

If she really said that, she wasn't a true best friend, or rather friend, at all.
Best friends never hide things from each other and even if you guys were to fight over a certain issue, at least you guys confronted each other.
Maybe instead of confronting her fiercely tmr, you can sit her down and talk to her nicely. Ask her why it's that way and did she mean what she said.
If she says sorry then I guess you could give her a second chance and work things out again, but this time, really talk about your feelings to each other and not hide a thing because other people could use that tension and use it against the two of you.
If she still does it the next time, or doesnt even say sorry, then you would know that she's not worth it and if she continues being your friend, she can sabotage you in many ways in the future as well.
It hurts, but it's for the best.
It can always be a blessing in disguise.
But before you take actions, it's always good to think first.
Like the peribahasa, Sesal dahulu pendapatan, sesal kemudian tidak berguna.
So, all the best! (: I hope you'd be able to settle this soon!

In situations like this you really find out who your real and bestest friends are. If she really were your best friend, she wouldn't confess to your boyfriend to begin with. What's in it for her if she gets what she wants? She loses a great friendship for what? I just don't think it's done when a friend (or best friend in this case) interferes in your relationships, that is not what best friends do even if she likes the guy. It's her problem to deal with it and get over it. Two, the fact she is saying nasty things behind your back is another thing that makes her less worthy as a friend, friends don't do that and stick up for one another, but she doesn't cause she's playing her own game. Maybe you should be a bit more careful calling her your best friend...Ive been there done that...Friendship is a valuable thing but she clearly doesn't see the value of it to begin with. Think about it: she rather has YOUR boyfriend than your friendship....NEVER become a second choice girl ;) it's hard YES, I am struggling with it myself too at the moment (Ive seen tonz of close friends go) but one day they will be sorry they let go of a friendship you once gave them....like I would say: I believe in Karma and she will take care of her sooner or later...what goes around comes around!! Don't let her interfere in your relationship....she's your best friend, she should respect you as a friend! Maybe she is not the bestest friend you thought she was....another wise thing: you'll meet your bestest and lifetime friends most likely after you 20's....

Wow. I feel like I'm in the past .-.
This past school year (6th grade >.<) My friend liked this guy named Nolan. Me and my other friend (Joanna) were like 'Whatever' We'd never met him. Then, we found out he was really cute, but I already liked someone else. Joanna was a and went after him, and actually fell for him. When Jo told me and asked me not to tell Megan (the one who likes him first) I was like 'I won't' But of course I had to. They hated each other after, and then I was stuck in between. It was like 'You're either friends with her, or me' Then we got a new girl (Melody) and Jo ditched me -_-
Anyway, before I knew it, was starting to like Nolan too, but I kept away, being a nice friend. They started dating, but when they broke up, I had this feeling Nolan liked me. He hung out with me more, and we talked a lot of recess. I knew Megan wasn't okay with it, so I told him and said we shouldn't talk as much, which he was okay with.
Then, I moved. Joanna decided to go up to Megan while she was talking with her guy friend and call them stupid, ugly, etc etc. Him and Megs were at the top of our class, and Jo was barely passing. WTF -_- Anyway, I couldn't do anything about it, but if I were there, I would've slapped her, no joke.
This was all way worse than it sounds, but a boy always, ALWAYS breaks friendships apart :/
OMFG. LONG COMMENT. OTL

Are you a malay? Ohhh that was such a bloody hell bastard girl. Woah, she's like an angel with a devil's tail. If I were you, I would use his acc and replied her, 'Oh really? You like me? thanks but aren't you her bestfriend? Why are you saying bad thing about my girl at me? Does it have to do anything with me?' I would do that.
Stay strong girl.
