how do you get over the loss of a friend?

[brandibabe]

one of my former best friends and i stopped talking about 3 months ago. the reason why is because her "best friend" and i got into a fight and since they are better friends and roomates, she stood by her, or at least it seemed. i got in touch with her recently and we had a long discussion over e-mail. alot of blaming the other person, etc., but in the end i told her its sad what our friendship has turned into after how close we were. after that she replied, ok whatever its pointless to try shit happens. i am angry and hurt that she would give up our friendship but i cannot force someone to wanna be with me. what do i do? how do i move on from this because by the looks of it, our friendship cant be reconciled.
