The problem isn't paranoia it's cowardice. Instead of telling the girl the truth and giving her closure in the situation you want to string her along and let her think there is a chance in the future for her to get with your friend.
I met a girl in 7th grade and we were good friends until we graduated. She told me before we went to college that if I asked, she would marry me. I knew I would never marry her and I told her straight up. I honestly cried because I lost a dear friendship and I missed her and she was hurt. 6 years later she marries another guy and now we are hanging out again. These situations suck but you have to deal with it and not give her the run around. A bunch of people in this thread have said to be honest and you ignore those posts. Man up and take responsibility.
