1 . Examine his body language.
If he likes you, you may see that he rarely turns his back to you, often leans towards you, and also looks at you a lot. If he slouches his shoulders when near you, he's romantic and cares about what you have to say. If he points his shoulders and pelvis towards you while sitting, he is definitely feeling something for you.
2 . Notice his eye contact.
If he likes you, he may either look away quickly if he is shy, or he'll try to catch your eye and hold it or make faces. This can be uncomfortable if you don't like him. If you feel like you have held eye contact just a fraction of a second longer than you would with anyone else, or if he looks away quickly, then there is something there. When he's around you and he says/does something funny and everyone around laughs, his eyes will flicker towards you for a second to see if you laughed, too.
