I really like this girl. How do i get her to be interested in me?

Well first off whoever came up with the idea to ignore or act like a jerk to a girl to get her to like you is an idiot. but don't bring up the subject of liking her just yet, for a while anyways. find out more about her through her and her friends. say if shes really into painting ask her to paint with you sometime or if you don't know how say you heard shes a good painter and maybe she could could teach you sometime. just don't sound creepy. after a while of this you probably will both know much more about each other and she could begin to like you. p.s this doesnt happen overnight take your time
