How do you know he has feelings for you but is in denial or scared about it?

Like this guy I’ve been talking to now wants to be friends with benefits says he doesn’t know what he wants atm or in life which okay and he says he cares for me as a person and he also gets really jealous when I talk to other guys or vice versa and he doesn’t want me having sex with anyone but him and he says he trusts me until I fuck it up he also shows a lot of affection but says we’re just gonna have fun and not get attached do u believe that we’ll consistently have sex etc and not end up attached or catching feelings? I don't know lmk please and I don't know what does he want why’s he so confusing I can tell he likes me but he never admits it
