I have crush a girl on facebook?

[Winses P]

I don't know why i crushed a stranger girl on facebook , we don't know each other and never meet before . I send her a friend request , that time she din't accept , later then i canceled the friend request , on her birthday i send her a greeting in message , she replied "Thanks" . I started to chat in message , sometime she not reply but sometime yes . I did ask "Can i send you a friend request ?" , she say okay , then we become a FB friend , later suddenly she liked my photo (random stuff that i captured , not my face) but no reply my message . So i continue send her message but also no reply , then on 31 December 2013 , i send a message "This is maybe the last message i send you coz i dont want to disturb you but i still will like you photo or comment it as supporting , if you want to chat but don't know who to chat , you can chat with me and happy new year to you" . She seen the message but also no reply . On 1 Jan 2014 , she posted a photo happy new year and i comment it , she like my comment later , reccently she liked my 2 photo again (my face photo and other photo) , yesterday she update her status and i comment it but she no respond , i sure she seen the comment !

Okay so my question is below :-

1 . Why i suddenly crush to her ?
2 . Why she no reply my message but liked my photo ?
3 . Issit possible to crush someone on internet in girl point of view ?
4 . What you think about this ?

Thank you and sorry for my bad english

Maybe she knows you like her but doesn't like you n just wants to keep you chaseing her
3 . Issit possible to crush someone on internet in girl point of view ?

4 . What you think about this ?
I think you should not pay attention to her it clear she's messing with you

You sound like a teenage girl. Stop overreacting and to me she sounds like she is just trying to be nice to you and you sound like your being clingy. I would stop messaging/commenting/ liking her things on Facebook. Just let her be and see what she does.
