Friend Zone

So I'm stuck in the friend zone with this guy I've known for over 6 years . Before we become intimate we didn't like each other to save our lives . One day things just sparked and we've became close . We spend everyday together like a couple would he says all the time he doesn't want a girlfriend or he doesn't catch feelings for females. He's the only guy I have sex with and the only guy that I give the time and day. Everytime we get into a argument he tells me I need to stop trying to play the girlfriend role which idk what that is or how I play that role. He always friend zone me and it's starting to get irritating . Can I get some advice I what i should do ?
