He said he loved me...what should i do?

Okay my best friend in the whole world is a guy named Brandon I met in 2nd grade (we are going to be juniors). I have been crushing on him since 5th grade. I always knew he liked me to... he loved to hug/hold me, he flirted with me, got jealous of other guys i liked/dated, he calls me baby/babe, he kicked my ex boyfriends a$$ for cheating on me and making me cry, etc. But we never dated. Well a few days ago we were in my room and he kissed me. Then he told me he loved me and well we had s*x...now i don't know what to do or say! We are hanging out tomorrow. Are we still just friends, friends with benifits, are we dating? I am completely confused...help?
