this hurts

I've been having sex with the guy I'm completely in love with. I want him more than anything and we talk all the time. Every second of the day we text but I just feel like he's sending mixed signals. He sometimes acts like he wants me and sometimes acts like all he wants is sex. I've tried acting straight up with him and asking what he wants but he keeps saying stuff like I'm not ready for a relationship and if you want anything more than sex we should probably stop and it's driving me crazy. I want him so much. What do I do
