A guy looked at me in a weird way?

We know each other and I was talking to him, while I was talking he looked at my eyes without breaking eye contact and smiling.

At some point he blinked very fast and then he did a "half blink", he sort of caught his blink before closing his eyes , so he half closed his eyes all while smiling.

Does this body language mean anything? Also we saw eachother in plublic another time and he say hi while walking, then he locked eyes for 3 seconds after I said hi to him and looked down smiling.

Do you think he likes me?
