for Zora's sake; let's hope she opted to not watch this catastrophe of a tv show! i think if she did, she'd think like all the rest of us, that he was going to choose Sarah. poor sarah, she gave it up just like that.
and i agree with voyager265 - i'd not be shocked to find out he did all 3 of them.
and to answer the question, i would continue to see a guy (and not evan for crying outloud) after finding out something like that but i'm far more "understanding" about stuff like that - more so than a "typical" woman.
evan's gross. i would never date him. and what about those dork friends they had on?!? "yeah, one time, we went to this meat market to pick up these hot girls... " ew.
