any guy decoders?

there's this guy that said he liked me and asked me out on a date last week bt I didn't know if he was serious or not. his friend teases us saying we're in love and I wanted to know what was up. yesterday after school I was planning on going up and talking to him about it because I had finally worked up the nerve to but when I actually was about to do it...I didn't see him after school.

so later that night after the basketball game I saw him and I got nervous a little bit so my friends pushed me into him and when we got outside I called him over and here's what happened.

me...drew I gotta ask you a question.
him...what's up Sarah Barah?
me...when you asked me out last week were you serious?
him...he looked at me for a long time, gave me a smile and started nodding. then he got nervous and asked if he made me angry by him asking me out
me...noo..I just thought you were kidding
him...no..I talk about you all the time..

and his friend standing next to him looked @ me smiled and said.....so this is Sarah drew talks about then his friend got on one knee took my hand and said its an honor....why did he kneel down and take my hand like that....what's up with that...
