What if i tell my bff i'm dating her crush - my other bestfriend?

I fell for my bestfriends crush, he fell for me. First time we pretended to date each other to teach her a lesson, I talked to him on the phone and he admited he liked me. We plan to keep it a secret, but what happens if that secret slips?

Best friends are really important and no good friend lies and keeps secrets. Be a good friend, she trusts you, tell her the truth. If you don't, your friendship might be lost forever.

Youre very right, today I couldnt bare to keep it a secret and told her - she cried and FREAKED! At the end of the day we got back as friends. But what if tomorrow shes still mad?

If she is a true friend she will understand and if your a true friend back you will tell her how it happened and if she isnt ok with it you guys should have never been friends
