AHHH! I think my best friend knows I like him...what does this mean?

ok my guy friend the last 8 months was acting super different. Like texting throughout the day, texting till 1am, chatting w/ me for hrs (once we chatted/texted/on the phone for 9hrs!), talkin lots in cl, teasing LOTS and being flirty etc. I tried to hint a lot that i liked him, but he didnt catch it or ignored it. So i did something super dumb & got on my friend's sn and told him a girl liked him and kindaa described our situation. Next day was the 9hr chat, and then 2 days ago, he asks if it was me. We chat forever, and finally i say "ur tricky, u confused me into admitting something once", & all he says is "hehe it was u...stop denying it hehehe" so i say it was me & we joke bout it kinda, but never talk about it realllly. Then we talk bout all the times we had a fight and laughed & opened up so much. We were almost talkin like a couple looking back on all our memories. Then he sends me a paragraph bout his interests and is like "does this make me interesting?"...
