I met this HB10 a while ago i go to college with she always tries to start convos i keep her entertained but stay the mystery and keep the convos short and sweet but how do i advance with out making her loose interest.

FYI This girl gets a lot of unnecessary attention so she has an arsenal of choices.

well if she does get alot of attension your goal is to never give as much attention as other around her. if she starts a convo with you again remember your body language. make her feel as if your leaving and tell her about a place your planing to go to on the weekend or whatever. see if she respond positively like she would be willing to go. then bring it back up when your saying bye and tell her she should tag along with you to that place you were talking about. Remember to tell her in a way showing her you dont need her to go because your going to have fun with or with out her anyway. remember this is when your about to leave. she has to be at the edge of her seat. know what i mean.

its good you havent showed much interest though but also remember once she gives you indicators of interest give her one back. just one. then bring her down. push-pull.
