^in general, if the girl is disinterested, u can't force her into being interested. most likely, she isn't the girl for u, & u have to move on. there are exceptions, but those are rare
p.s. note to all guys out there:if the girl seems to be ignoring u, then guess what? SHE'S NOT INTERESTED. there's no point in thinking that she *may* regain interest, so move the hell on. we only do the ignoring thing, because we feel bad & don't want to hurt your feelings.
