does he really like me.....

there is this boy at school that i like. he says he doesn't like me but always talks to me when my friend called out his name and i was so surprised
he waved at me looking so happy. as if he was happy to see me. i remember he was looking right dead at me it was akward for a moment i did see him looking at me but i was looking at something else in a gaze. think he wanted to say something to me. and every time when he's near me he always talks very loudly o tries to get my attention. we used to text eachother and stuff and talk. could he possibly like me? o he doesn't want to admit it?
