I think I’m being used

So me and this guy have been on and off for a while. We started to talk again in September but then stopped in December and started in January. We talked for months and he never once asked me to be his gf, I’m tired of the talking stage but I don’t want to ask him to ask me. I wanted him to ask me because he wanted to

recently I’ve been feeling like this relationship is all sexual, everytime we meet up is just for me to give him head and after that he drops me home and distances himself from me and I hated it so much. It makes me feel dirty and I’ve been wanting to stop all the sexual stuff but I think he’ll leave if I say that. He doesn’t call me anymore, he doesn’t say the sweet stuff he used to say to me and honestly this is making me lose feelings. I’m supposed to meet with him today for yk. And I’m done if nothing changes after tmr . I’m planning on distancing myself from him after today
