Am I supposed to support my best friend?

ok my boyfriend and I were going out for 4 monthes, but I found out he liked my best friend and he said he would have to think about it like it was a crucial decicsion. he chose my best friend over me and I was really really upset I know im a big baby when it comes to guys but I cried and I was wondering if im supposed to support my best friend? cause they lied to me saying they dont like each other! should I support her?

Absolutely NOT! You're so-called 'best friend' stabbed you in the back with your boyfriend! If I were you, I'd move to another state, because your life is totally going to suck....Unless.....You drive your boyfriend COMPLETELY INSANE by PRETENDING that you're happy for them, all the while acting like you HATE your ex-best-friend!!!....or vicea verca... whichever you think is the best bet... then the two of them will talk about it, and be totally confused... and then when your ex-man tries to pull you aside in class for a little one-on-one q and a, you can lay a big smacker on him and tell him that you've been dying without him! that way, they will be totally confused and the element of surprise will totally be on your side.!
Keep me posted on how your scheme plays out, ok girl?
Until next time, chicka!

No -im sorry but you must be crazy if my best friend would do that to me she wouldnt be my b/f any more she would be my enamy I cant belive she lied to you how can you be her b/f if she went behind your back and stabbed u ??????????????????????
