How can I get him to notice me?

OKAY HERE IT IS I LIKE SOMEONE AND I don't know IF HE LIKES ME OR NOT I BET HE DOESN' BUT HOW DO I GET HIM TO NOTICE ME WITHOUT HIM KNOWING I LIKE HIM I WANT HIM TO LIKE ME BEFORE HE FINDS OUT I LIKE HIM HELP ME PLEASE I LIKE HIM A LOT A LOT

FLirt with him, see his reaction, when you are not near do you feel him watching you, do his friend laugh when you walk by but him, is he a shy guy? or an outgoing guy? I mean there are so many hings that means a guy likes you.

He he blushes some,
does he ever talk to you, get to know him but not be " Just on of the guy" thats all I can say ...

Watch his reaction to things, if you see him watching you then he likes you, If you are talking watch his eye, are his Iris big? Do they move, does he make eye contact?

how about you just tell him you like him, you are 19 this is childish that you cannot just outright tell him that you like him, if you want to be a baby just write him a note and ask him if he likes you and draw the little squares with a yes and a no on it

Talk to him.
But be yourself.
Dont Act.

If in fact this question is from a 19 yr old! (which to me sounds more like middle school)

who says im 19
