You've probably heard of this happening countless times.
My best friend Steve likes this girl who he's friends with, and we hung out with her yesterday. By the end of the day she was all over me, to sum it up. When we walked back to Steve's house, it was just me and him and I could tell he was hurt because he wasn't talking at all. I told him that if he was pissed off that I understood, and he responded with "alright." Today, I hung out with her again and we are now going out.
Steve and I have still been joking around over Myspace to each other so it doesn't seem like he is too hateful towards me right now, but I don't know if he knows that we are going out yet.
So I want to know if you think I am wrong for dating her in the first place even though I know that my friend likes her, and if you can give me any advice to help maintain my friendship.
