Is he into me or not ?

This may be long but I'll try to make it short. There's this guy that I extremely like who goes to my school.His very well matured,hot and seems to have a great personality, but i dont if this means he likes me or finds me ugly. In the begging when i first saw him , he looked at me for roughly 3 seconds before turning away. Later on he constantly stared at me from the corner of his eye. Followed by whenever i walked into the class he would stare with a normal reaction but at the same time a slight smile, I try not to look at him too much because i get excited and go hypo (lol) . A couple days later my best friend added him on Facebook and saw all these pics of girls like kissing him on the cheek hugging etc.. Then i added him , and all his tagged images were deleted. Also when i added him his gf sent him messages etc and then after awhile were deleted im not sure if it was him or her. Now, whenever I see him he just stares and i ask my friend "do you think he likes me" and she answer " he looks at everyone" . This does not make sense to me may someone please tell me does this mean he likes me or just looks at me as a normal person.
