Shes says she is over me...but why does she ask me things like this?

My GF who I dated for 7 months claims she is over me and says she has no feelings for me.... Yet she still texts me and ims me when i get online... when I hint about maybe getting back together she instantly says no and makes up these excuses.... However, she still loves to ask if I am still seeing that girl I dated after her and wlso asks if I have dated anyone recently or hooked up with anyone etc. Does she still have feelings? We have not seen each other in 4 months... We are going to sit down for a dinner in the next 4 days.... Any ideas on why these questions get asked and if she still has feelings?
