I had a best friend named Jessica. She was a great friend, because she was always there for me. Even if she didn't wanna go, she would go just to give me company. Every person has a flaw, and her's was she was very high maintainence, lied a lot, and was very childish. My parents never liked her much, but I loved her like the sister I never had.

So we broke apart and did our seperate things.

After a while, when school started again, I started hanging around my friend Irina, who desputed with me a year previous over a stupid issue. Anywho, we started hanging out again, even though I knew things could not be like they were before. Things were going great, but her ex was my close friend Chris. They were still hanging out, but he still loved her, and it was KILLING him. He was depressed to the point of suicide (which really hurt me, because I didn't want to loose him). Well, he started to feel better about the whole thing, and they started paying attention to only each other, and myself and my other friend Kiara felt kind of left out. We confronted them about it (kindly, of course), and they said they would try and change it. Nothing has changed, and I'm getting annoyed, because, this is the main point:

She always flakes on me.

We'll make some good plans, and then either the day before, or a couple of hours before, she'll call or message on AIM, and let me know she can't make it. Now, I know that on some of those days, she's gone to go hang out with her ex-boyfriends. I didn't think that was very nice. Flaking on me to be with her EX's. She's done some other things to bug me, but thats not the issue. Needless to say, I've gotten so fed up with it, I've just stopped talking to her altogether.

I've discussed this with my mom (because I know she'll always be my best friend), and she's helped me a little, explaining I should expand my circle of friends and not rely on one person to be my bestie.

But my question is:

Are my expectations for friends too high? Do I expect my friends to be more than they can be?

The only thing I really ask is that they be truthful, follow through with their commitments, and to just be themselves.

Opinions? Advice? Much appriciated.
