Should i pursue one of my ex-girlfriend's friends?

I am in love with one of my ex-girlfriend's friends and she and i are friends. I don't think she likes me, but my real question is, should I risk it? i can't focus on anything, because she is in my head all the time!

No, don't come in between two girlfriends. You don't want to be in that position, you'll never hear the end of it anyway.

i meant should i risk the friendship? the girlfriend thing is couvered

yah you should! lifes tooooo short to just ignore your feelings! and confront her make her no u really like her by letting EVERYONE no ur together (if she accepts) it will make her feel special!
