first things first, analyze your feelings to the girl. do you really like her? I mean really, really like her? not just because you enjoy the same hobby but because you like her as she is. coz' maybe you just like her company coz' of sharing the same interests... after analyzing and realizing what your true feelings for her then (if you really, really like her) tell her your feelings for her and tell her you'll wait for her until the right time she's ready for another relationship. you don't need to hurry her coz' she maybe just afraid for another failure relationship...for now. but if you don't wanna loose her like the other girls, stay beside her and be a good friend for her. make her feel that your always there for her.
