give me some opinions guys 😭

Well lately I been talking to this guy. We made out before we also had sex before. But I wanted to make thing official with him. Whenever I ask him he said he is not ready for relationship... I just feel like he is using me for sex.but at the same time I get why he doesn't want another relationship rn because his ex girlfriend was pretty crazy. And when I ask him I felt that he is using me for sex he said he wasn't he said he likes my vibe and stuff when we hang out .Do you guys think he is just using me for sex ? Or Is he really not ready for another relationship ?
