When a guy "grooms" himself does this mean he's interested?

Anonymous
A few things I've noticed with my crush today:

He would put a hand on my arm or shoulder and playfully shove or nudge me

He would run his hands through his hair

We hug when we say goodbye and he would kiss me on the forehead a few times and play with my ears

Sometimes he'd flick my nose

What do you think?
