my best friend kissed me and idk what to do!

so i've known my best guy friend for about 3 years. we really started hanging out a lot this year and became closer.. as friends. he would always flirt with me a little and i would play along, but it wasn't anything to serious. so the other day he came over to hang out and we were sitting on my bed downloading music on my laptop and out of nowhere he goes "would you get mad at me if i do something?" and i turned to look at him and didn't even have time to answer because he just started kissing me. i went along with it but then pulled away and told him how weird it was. but then we kissed some more and it was getting pretty intense.. we only kissed though. idk what to think or do. like we get along so well and have a lot in common but idk how a relationship would be. i don't even know if he would consider us having a relationship. he just kissed me.. he didn't even ask me to be his girlfriend or anything. i'm scared he's just playing with me but idk... this happened yesterday btw, and last night he kept signing on and off of aim and then he sent me a music file of our favorite band and then signed off.. and today he hasn't talked to me. i feel weird, but i like him. ughh.. sorry for the long post! what should i do? we might hang out tomorrow, but he hasn't even talked to me so idk. he's online now but on away and i don't want to send him a message first. oh, and while we were kissing i asked him why he did that and he told me because he wanted to. he said he wasn't just using me but idk what to think.. i've never been in that situation of a friend just going and kissing me. he told me how we have so much in common and that's what he likes about me but it was just so awkward. i told him he didn't even ask me to be his gf and so he asked me while we kissed and i told him it depends but i never gave him an answer because idk what to say. i do like him and i would go out with him. i feel like he only asked me to be his gf because i told him why he didn't you know? i'm only afraid because i always thought he played around with girls but with me as a best friend it was different. like i think i'm the only girl best friend hes ever had.. but for some reason i always got that he wasn't bf material.. not just for me, but for any girl. like i would always think he wasn't serious. but he told me and i quote "why do you think that about me? you think i'm just gonna forget about you tomorrow? you're my biffle (we call eachother that lol as in bffl). i'm not like that and you should know i just joke around. i'm like the biggest loser." lol.. this is weird for me. i wanna talk to him.. but i'm scared of getting hurt.

Paragraphs would be helpful.

Making-out causes an inability to break thoughts up into paragraphs (see loquieromuch for another example), it's a side affect of the pregnancy that kissing causes.
