Accidental or genuine signs?

Ok so I really like this guy and he tends to flirt with everbody without knowing what he's doing. Like hes so genuinely sweet he'll tell a girl she looks pretty and be completely oblivious to the fact he's leading her on. But to me he's mire flirty and he always hugs me and makes excuses to touch my face and dies that fake kiss thing where you put your hand over their mouth and kiss your hand.. Just to see my reaction. Does he like me or are these signs accidental?
