Man, if it's girl trouble...especially one involving a friend, I know how ya feel. Look at it like this tho: if someone says they are ur bud and they get with a GF or and ex that you haven't been broken up with long, they really aren't a friend. They are just about themselves. And if a GF does that...you really don't need her anyways cuz sooner or later she would f@ck you over anyways. I know you just want to bash their heads in, but you are better off to forget it, lay the GF of the dude that screwed ya over first chance you get, and try to get with the best friend of the GF that did it to ya. After that, everyone gets a taste of their own medicine and bygones can be bygones.
