here is my situation. I have a good friend that has a lady friend that is pretty hot. he has known her for several years and even admits that he doesn't have a chance with her and they are just friends. I have been getting 'buying signals' from her. but i keep my distance because i value the friendship with my friend. my friend has even said that he thinks of her like a sister and it makes him uncomfortable when guys flirt with her and he is there. I was wondering what 'rules' apply to this situation. i feel pretty confident in my decision to stay away but i was wondering what everyone else thought.
