Student Exchange Programs

Me and a girl (european exchange student, if that is even important) work together at our student job on campus, and we HAD been friends for over 2 years. So LONG story short I fell for her but she wasn’t interested. After I asked her out the first time and got rejected, about a month later she started being really friendly with me eventually she asked me to help her look for a car. Well a few weeks and a lot of my time later she had a car and I had helped register it smog check the works. Well I stupidly saw all this time she was spending with me as a sign she liked me so i asked her out again, WRONG. A close friend pointed out to me that this was just one time out of MANY where this girl was just using me because she knew I liked her and how when ever I needed something she was always busy. I am more ashamed that I let myself become her personal lap dog and let her walk all over me. I could deal with her not reciprocating my feelings but I was angry that she abused my kindness like that because she knew I liked her. I have learned a lot about her since then that i did not realize before that would probably turn any guy off of her (she is a user, a tease, manipulator, future gold digger,etc..). So now skip forward a couple months and believe me I am no longer her ‘go to guy’ for everything thing. I don’t even speak to her outside of work. she probably still thinks we are BFF’s like we used to be but she is strictly a co-worker to me now. we are back in school and all of a sudden she is dressing really ’scandalous’, ‘revealing’, ‘trashy’, ’slutty’, whatever you want to call it. I know she is doing it to attract attention from ‘whoever’ at school but the way she dresses in completely inappropriate for work. and no matter how much I don’t like her now it is hard not to stare when she dresses like that. Why would she even dress this way around me, especially with the awkward past we have? (she can dress however she wants at school but I don’t appreciate her being that way around me at work) Besides would you dress that way around a guy who probably still has unresolved/mixed/confusing feelings about you even though you don’t like him?

P.S. I may not have to worry about it though because I have informed my supervisor about her inappropriate work attire.
