I dumped Rob, going out with Zack, love Tristan. You think I'm screwed? Just wait ... they are all younger than me! Rob and Tristan by 2 years and Zack by one. Tristan likes my best friend. Rob thinks I'm stabbing him in the back, and Zack is oblivious to everything. I dated Tristan for a while ... he dumped me twice. Zack isn't the nicest to all of my friends, and NO ONE likes Rob. Someone help me?
