What should i do???

ok i have a male friend who is totally hott & we've been friends for 4 years & wen i very first met him i knew it was love @ first sight. well we talk constintly & at first he was a player & now hes finally realized its time to stop being immature, well hes known ive liked him since the day we met still we jus stayed friends. he had das (dentention after school) & he didnt want to go by himself so he asked me if i would go knowing i would be able to spend 3 hours w/ him i said yes. well afterwards he told me to come with him to his locker, i did, so i could put my stuff up too & he started walkin behind me with his hands around my waist & wen we got to his locker he kissed me. we moved to the makeout hallway & continued kissing, he even asked me if i wanted to go further when i replied "no" we continued kissing after like 30 minutes we went home. he called me that night & told me it was a mistake & not to tell anyone. i still love him & he doesnt love me... what should i do?
