<human>: So I have liked this girl since freshman year of high school (14 years old).  I am now 21 years old, and we still talk all the time.

We would hookup all the time, off and on in high school although we never really "Dated." A couple years ago she started dating my best friend. Which I was fine with... I actually hooked them up. Him and I grew up together since we were babies. 

They broke up in January of this year, and I have been hanging out with her more. We hooked up last night (just oral, no sex) and she wants to go all the way tonight.

I really don't want to do this to my best friend, but I am so attracted to her and our chemistry is great! What do you guys think?
