Sigh. I know exactly how you feel and, if you are anything like me, this situation probably pains and saddens you. Just you remember that your friends love you (even if they don't have the best ideas at time). Also, keep in mind that people have crushes on other people even when they are in committed relationships, that's perfectly natural (you don't stop being a girl when you start dating a boy, sheesh).
On the one hand, I feel you should be able to express yourself freely; and on the other, I understand your bf for being annoyed at the situation (though if he did read it carefully, he would be flattered at the way you described him ;)
Anyhow sweetie, just wait a little longer, thing'll straighten up in the end...
(let me know if you want me to remove this post)
