When a woman you are friends with isn't interested in dating, but expresses slight jealousy or a fear of being "replaced" when you spend time with other girls, does that ever develop into something positive, or is it predestined to turn sour?
Edit:Maybe possessive was too strong a word. Right now it's mainly joking, and her expressing slight jealousy. Still confusing though. Thank you for all the answers though. Definitely has given me some stuff to think about.
