WHY DOES HE DO THIS??? ANSWER 10 POINTS!!?

I like him so much. He liked me to, then we both STOPPED liking each other. He was mean when we didnt like each other. Then i began to like him again RECENTLY. He has been being so nice i was just going to tell him. THEN today all the sudden he was telling me i was annoying like running up when i hadnt been talking to him, not even thinking about him and he ran up and said uhhh shut up your so annoying! WTH is up w/ that!!!!!!!!! Then he was staring at me while we were sitting down in class and was doing things way out of the ordinary like messing around with his freinds. Was he trying to get my attention. Did he out of nowwhere just LOSE interest. Oh yeah and when he was nice to me i KNEW he liked me it was so very obvious but know im confused? !10 points!!
