GIRLS, do girls just like the jerks or do they.....?

I think it is a typical excuse used to keep someone at a distance. People often use that excuse when they don't want to hurt someones feelings or they like the attention you are giving them but don't want to reciprocate. I would back off and not call or anything and see if she comes around or not. Sometimes absence is the best thing to jump start that person into action, if not move on.
