You think I should back off?

There’s a guy who likes me, though i am a bit confused but he’s after me since 6 months.
I couldn’t understand whether he genuinely likes me or just taking it casual because he would not take things very forward and also we hang out like friends.
He says he likes me but he isn’t head over heels for this, like just not prioritise this thing but he genuinely shared it with me.
Although i also said i liked him but the real reason is I am attracted to him physically more than emotional.
I am getting confused he doesn’t talk to other girls , says he likes me and also treats it like a natural thing no big deal, no pressure of coming in relationship.
I just think if i am attracted to him physically then I don't know what to do.
