you are very smart man. +K my ex did this to me with my best friend because she was pissed that i would not get back together with her when she broke up with me in the first place. well he told me about it before it happened, and i was like eh fuck her i dont care, do some funny and weird shit while you do it... and so i turned around and slept with 4 of her best friends, all very very good looking girls that were jealous of her when he dated me. woop payyback was a big bitch.
my buddy and i laugh about it every time we see each other.
