Kiss and don't tell

Last night I was over at pizza hut and just hanging out, and then I went out side with this girl who I really like, but my best friend also likes her. We talked for a couple minutes and before I knew it we were making out. After we finished we went back inside and just hung out somemore. Then on the way we were sitting in the back of her moms car as her mom was driving home and we made out again. I feel so bad cause she said not to tell my best friend. It makes me feel so bad that I'm hiding something from him (even though he has made it a practice of hiding things from me). Well I don't know what to do and now that girl hasn't talked to me and is avoiding me I think. What should I do??

Put yourself in the position of your best friend, would you want him to tell you if he had done the same thing to you? And how do you think he will feel if he finds out later from someone else? And i dont wanna sound harsh but it sounds like she just used you the other day, but i dunno...
Good luck xoxoxoxox

David I hope your werent talking about me.Because if you were.You already told me.I swear not to tell her.I hardly even talk to her anyhow.And besides if I would have done that with a girl in your class I would have told you the next day regardless if you knew who she was.And I know how she acts so if she kissed you then she likes you.

Anyone is up to a kiss. I'll kiss and tell. But in your case. Eh. i'd tell my friend. Because i would hate that coming back to me, and if he's really your friend, i promise....He'll get over it.

it sounds like teh chic used u... usually guys say the "dont tell anyone" thing
