I've already had to do that, more than once.
First time, 3 people told me the same story: "She made out with Savannah on the bus!"
Next is, he actually told me he cheated, I broke up with him anyways.
Third one, much more serious than the last two relationships, he had to move to Michigan. He promised to call everyday, or at least every other day, he promised to make it work. He didn't call me for more than 2 weeks.
I message him on facebook. I text him. I post on his wall.
Then I see some chick tagging him in her drawings of hearts. He deleted my wall post. I asked a friend to ask the chick if they were dating. They were.
Me and my guy friend sent brutal messages.
