Who should I choose?

okay so I like this guy but I dont think he likes me. and my other REALLY good friend who I sorta like just asked me out. I dont know what to say, my friend likes him and she told me to F** off and called me a b** when I asked her if she still liked him. I dont know what to do..I guess I wouldn't mind going out with him, and I think we would be happy because we already have such a good relationship, but I fear the wrath of my other friends friends, which is bascicly the whole school. if anyone has ANY advice I would apprieciate it SO much. thanks!

I think you should choose your friend since you know so much about him.
