mate, reverse the tables and play games on her,
when she asks you if you have time to meet with her, tell her that your busy, but youll call her when you can be bothered, and NEVER tell her that you like her again, it gives her the power, and a guy that doesnt take control of his surroundings are not attratctive to girls,
just do little things that let her know that shes not the one wearing the pants
small things such as :
1) ending conversations on the phone
2) ending meetings
3) not glueing urself to her when she leaves
4) dont compliment her all the time
basically show/tell her that her mind games are a peice of shit, and youll never play into them again... and that youve got beter things to do than be her callboy
try doing that and youll notice an almost immediate change in her attitude, and she might even start asking YOU out.. in which case dont answer immedietly, but take a while to "think about it"
and good luck mate
