Help! Advice needed!?

I just caught my bestfriend doing foreplay with her boyfriend's bestfriend.


Should I tell her boyfriend or someone about it?!? BTW my bestfriend is 15 and her boyfriend is 17Help! Advice needed!?
Be loyal to your friend. Don't even get involved.Help! Advice needed!?
stay out of it, you are not involved in this right now and are therefore not at fault. Even though you did nothing wrong, telling will get more then a few people mad at you. You would be suprised but her boyfriend will end up mad at you somehow and even worse you will be short a bestfriend. How could she be your best friend and you have to ask this question. Your on her team not his.
best bet is to stay out of it. your friend was wrong in doing what she did, but, her bf will be crushed by the news. let him find out some other way.
I would def. tell her boyfriend about it, or if you are nervous about doing so, at least hint to him. Say something that will show a clear message to him, that his girlfriend isn't loyal. Tell him to watch what she does around him or that you wouldn't leave him and her alone, or tell him to ask her what she did the day that you saw them foreplaying. It's awfully hard to lie to someone's face when there is an eye-witness standing there also.
