When you know a friend's a bitch...

There's just some friends that I KNOW better than to put any sort of faith in at ALL, yet somehow I still do and I still end up getting hurt. One of the girls from my last class is a bi-otch with a capital b, and I knew it from the beginning (when she got upset with me for going to Sea World with my family over studying with her and our other study partner, and gave me the cold shoulder instead of telling me she was upset). After this last class I've sent her a few emails, one to try and arrange a dinner between her and the other girl, and a few just to check up on her, as well as leaving her a few voicemails. No response. Tonight I find out she's taking the next class with the other girl we studied with (who signed up a long time ago) and I STILL haven't heard from her. It should really come as no surprise to me, but it still stings just a little.
