I like my best friend.. and he told my other friend he likes me. But I don't know what to do.?

Just about last week, my friend had asked me saying "Do you like _______, because I think he likes you", and I replied with "yeah i do.." Then shes like "really? omg! yes! tell him! because i don' t think he likes you.. i lied,.. i know he does. He told me but i won't tell him what you told me, i'll leave that up to you". And this news really surprised me, and then i thought back of when i could kinda tell, but i never thought anything from it. Anyways, it took me a few days to get over the awe of it all. But over the days i was getting use to it, he was like kinda really obvious about, but i didn't know what to do. So, im guessing that it just looked like i didn't really like him. Anyways, another friend told me just to wait for him to tell you he likes you. I agreed, until i thought about it, and realized, that he mightve liked me all this time, but didn't say anything. So why shoould i wait? Its not like he doesn't know how to hide his feelings. So i want to tell him this week, but i don't know when. He isnt at school like half this week, and i kinda get lonely haha. I could tell him, i just don't know what to say and i don't even know if he likes me anymore! Im quite confused myself... haha We are like never alone and we are surrounded by people we know. So obviously no privacy! I kinda feel like the time has ped, and that he figured it wasn't there or something.. but it IS! Another thing is that sometimes he stares around, but of course he could be thinking about something else, but i ask him "are you okay" he would be like "what?" "yeah, im just tired". And im like... hmmmm.. haha I also text him almost everydayy. So i need help! I don't if he still likes me, im kinda insecure about that. And i don't know how to tell him, or ask him "who do you like" or somethingg. Another thing is that he has a lot of friends that are girls, and i get jealous at times but i really try to not to. I almost feel like this is all just a dream....:/ Help?
