There is a girl I know who hangs out with our little group occasionally. She has started hanging out with us a little more and has started being pretty flirty with me. I'm not the best at reading girls, and I started thinking she probably liked me. A few other friends have also noticed and told me that. The problem is that one of my friends has liked her for a while but never gotten the guts to ask her out. I'd like to ask her out some time, but I don't know if it's right to do that to one of my friends. What are your thoughts?
