Friend's personality change...?

I have been friends with this one girl for about 2 months or so, and have treated her great (she has even commented on how i seemed to be as perfect as a man can get). However, about a week ago she met this guy who is a complete jerk towards her and she has become very standofish/jerky towards me yet is clingy and almost worshipping towards him. What is going on???Friend's personality change...?
Its the jerk doing it to her. It could also be drugs. One of my good friends from high school completely changes when he started doing cocaine and drinking 8-10 beers a night. He treated his girls like complete sh-t by my standards and I never could figure out why they stay with him and how he always had them lined up. He's playing with her self-confidence and insecurities. Thats how they work 'THE JERK'S GAME'. Its horrible isnt it?Friend's personality change...?
Shes just caught up i think. you should bring it to her attention let her know.
