I need your input??? (boys only)?

Okay, So I dated this guy a few months back, He told me he loved me after a few weeks of dating, and I didn't say anything back, And he broke up with me three days later, During those days he didn't say a world to me not a text or a phone call. ( I really loved him too I was just to scared to say it at the time.) He told me he loved me one day then breaks up me the next, Why? He didn't really give me a chance to tell him I'd loved him back. We go back to school and pass each other in the halls, he pretends like I don't exist, and he displays indifference around me and it hurts a lot. is there a way we can be friends, even if he is really indifferent toward me..???
