I'm in a badminton club for years. I've a large number of acquaintances more than friends there. I know one of the women has liked a man there for a long time but I heard through someone else he has no interest in her. Recently, to my surprise, he has asked me if I'd like to go for a drink sometime. Now, I've never thought of him in this way before, but he's a nice guy and I think I'd like to. However, I'm a bit hesitant for fear of upsetting this woman that likes him and I'd hate for there to be any awkwardness. Should I just say no?
