There is no set person that is suppose to do anything. When/If you feel its right to say it you just say it. If someone does not say it back right away do not be sad or worried as they just may be shocked, shy, nervous and need time to think about it.
You just have to tell her. She will appreciate it if you do. Girl's love it when a guy says they love them!!!
Simple you just be yourself and if she doesn't like that then she probably isn't the right girl for you. However if you REALLY love her then just be honest about how you feel about her (or you could just do what other guys do and smile at everthing the girl says).
I'm going to have to say that it entirely depends on the girl.
if you love a person you will wait. if you fall in love with another then you leave and she will regret her lose
She wants to know if he loves her first, before she says it. She doesn't want to catch him off-guard by saying it before he does. Or she doesn't love him like she says.
tell her you love her and see what she says
A girl LOVES it when a guy puts his arm around her and says 'I love you.'
Well I do not know. he wants a girl that has a gorgeous smile and a girl that has a sense of humor says that he will just fall in love with a girl that he really likes so it is yes and no
It means they are deeply in love with you.
just don't do anything
Tell them how you feel. Do you love them? If not tell them.
you sould ask her what does she mean by that ... O.o
