Forgetting Sarah Marshall

Im sure most of you know that a new movie recently came out called "Forgetting Sarah Marshall." It was written and produced by the same people that did movies such as "Superbad" and "Knocked Up" I don't know about you but those are two of my favorite movies. I would encourage all of you to go see the movie as soon as you can. This post I guess goes towards the guys. If you were in his shoes, your girlfriend is leaving you for another man how would you react. I don't want to give the movie away so Ill wait to hear back from those who have seen it. I have a friend whose girlfriends left him for someone else. He found out she had been cheating on him on top of it all. Needless to say he was very upset. Right when he was starting to get over her she came running back. Girls please feel free to explain the speech of how you were dumb and did not realize what you had. I say its all lies but he bought right into it. So my question is this would you have taken her back after all of that or done what had happened in Sarah Marshall. This post is pretty lame, but I dont know what to do about my friend. Shes obviously not right for him.
