Backstabbing/jealous girls.

Okay, so my boyfriend's best friend(I've known him for quite some time) has a new girlfriend, we go to the same high school but we've never talked prior to them going out. I started talking to her on MySpace and we were gonna hang out at warped.

I...

went up there with my boyfriend, and a big group of his friends including her boyfriend. She didn't come until like 2 hours later, and once she met up with us she totally blew me off. She gave me dirty looks and didn't say one word to me. We all figured she was jealous because of the fact that my boyfriend and I were more lovey and stuff, and hers was kinda ditching her.

So I forgave her, and like a week later she tells one of the guys in our group a HUGE secret that I didn't really want anyone to know, but I let it slip to her by accident.

She keeps apologizing and saying she didn't mean to do all these things, but I don't trust her at all nor do I really want to be friends with her. It's going to be awkward though because if her and her boyfriend last long enough she'll be at our lunch table, talk about awkward.

but I'm also a horrible grudge holder, and I never forgive. So I'm wondering if I'm being too harsh, or am I right for not being her friend anymore?

if you read all this thanks cause I know I wrote a lot, I tend to babble on. haha my bad.
any advice is appreciated.

A.Amity.

I think it matters on what the secret or water it was

hmm...well this is a very awrkward situation.
if you and your boyfriend are more loved up then her and her boyfriend then she is going to be very jealous. and when people are jealous they usually get a bit angry and try to do things to get back at you or to stop you from being soo loved up.
my advice is to try and help that girl and her boyfriend to be more 'loved up' and then she will have no time to spread things about you. try talking to the boy and tell him that him and his girlfriend are a bit distance and should act more like boyfriendgirlfriend, without saying it in a too harsh way. then maybe try to say the same to the girl and if they end up more loved up she should then forget to be nasty and jealous to you.
if all else fails, I then suggest to just forget the girl and lead different lives and just say to her you had your chance and you blew it.

I hope this helps (:
