Come to the realization that you are never going to get this women no matter what if you don't go up and talk to them. Make it happen or it won't happen. Besides, if they aren't friendly with you, than you learned something important - they aren't all you're making them out to in your mind. Test them - see if they are really worth your time and effort.
