In need of advice.

So I've been fooling around with this guy for a couple months. Everything started out physical and now we have both caught feelings for each other( we had this talk). I know that I want to be his girlfriend but he's not ready for that move. I often ask him what he wants with me and he responds with "I want your body and a little of your mind."

Anyway we do all sorts of couple stuff together

-we cuddle

-he helps me shop/pick out clothes

-we go out on dates like out to eat/visit forest preserves/take pictures together

-we study together

-we phone and video chat/text all day (about normal stuff and physical stuff)

-we often talk about our feelings

BUT we haven't moved forward.

He's always calling me things like chocolate chip, tinker bell, or his little flower

-he's the type of guy that's into bdsm BUT picks not to throw me around like that.

He says I'm his but he won't agree/admit when I call him mine.

(We are two different races and religions so I kind of feel like he might not like that)

Can anyone tell me what's going on ? Is he just playing with my feelings ?
