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 hoặc tries to get my attention. we used to text eachother and stuff and talk. could he possibly like me? hoặc he doesn't want to admit it?
