It could be a number of reasons including it may just not be meant to be. You should find someone who loves you as much as you love them.
ask them out and the only way you know that a girl doesnt like you is she doesnt smile at you or say hello
He could really like the girl, and just be denying it, or is just a player and really doesnt like the girl.
it means she doesnt like you, and that she isn't feeling the same way as you.
you can like her but that doesnt mean that she doesnt like you too
ask her if she wants to have sex, if she doesnt, shes a waste of your time:)
Find another girl that you like that DOES like you.
then she wont be a proper freind if your freinds mak e her chamge the way she feels about u.
You cant force anyone to like you I mean I understand that you really want her to but if she doesnt then she doesnt but if you prove to her that you like her and you can make her laugh and feel comforted and protected around you then you might get her to.
She eithet doesnt like u the way u like her or the ring doesnt fit well
You ask her. See how she feels. You might find out she feels the same way.
I'd choose the girl.
Spit it out.
