Ive been with my girlfriend for a year and a half now and we've been getting in arguments alot.?

can someone tell me if she still loves me or what she is doing? we are broken up at the moment and she still talks to me and i told her i want to hear her say we are over (i initialized it at first) and she wont say it... so im stuck wondering if she still loves me or if shes wasting my time, cause she says and if i dont meet her demands for once then we cant be together and when i deny her of what she ask she just gets mad and then acts like she doesnt care but still trys to talk to me and ask if i changed my mind.... x_x can someone tell me whats going on and what i can do?
