Girl pregnant!!

Ok so my friend and his girlfriend have been dating for almost a year and they are saving it for marriage. Well me and his girlfriend have been doing some stuff in bed and she just texted me saying she took a pregnancy test and it came positive and i am the only one she has had sex with in over a year. My friend is gonna kill me when he finds out what should i do?

You are a really bad person...

Mingliao, please note that we're here to help people solve their problems, not just post a negative judgement. Please don't ever respond in such a way again, it's very unkind and wholly futile. He's not a bad person, he's done a foolish thing. He knows that. IT'S WHY HE'S HERE.

IMGONNADIE91, *Why* have you been helping your friend's girlfriend to two-time him? Your answer might well have a bearing on what's apparently going on.
