I think you did the right thing in trying to get the cubby dude to tell the guy what he did with his girlfriend. you def. don’t want to be stuck in the middle of this especially if he knows you don’t like his g/f very much…he might think you are trying to break them up because you don’t want them together, and if he doesn’t want to see the truth…he won’t so…def. make that dude man up…good luck!!
