I like him and I think he likes me but...?

ok i'm trying to make this short! haha i'm thirteen by the way(: so I have this thing for my best guy friend, he like always flirts with me, follows me around like a lost puppy, there was only one seat left in the cafe lunch table and instead he just came and sat down with me. he looks at me wayy too much, we are always talking and everyone thinks we are going out haha. we will like be at the track and i'll be on the other side and he will just stare at me, its wierd but I don't mind it haha. whenever we talk he always makes direct eye contact with me. he knows i like him cause I told him i had feelings for him a few weeks ago when we got in a fight but he like didn't do anything about it. he just became more clingy. So today in homeroom (changing the names just in case haha) it was me and him and we were just talking and laughing and looking at stupid stuff on my phone. and like my friend Jeremy was like oh look at the two lovebirds! and our teacher was like oh who Jeremy? and he was like Kristina and Cody! and she was like awww and I was like nooo hahaha, then like whenever we lined up to go somewhere (we've been in homeroom all week) he always no matter what stands next to me and my best girl friend elizabeth is like yall will never be just friends yall are always flirting look at yall. and so i had this note and i was like here u can read this part and like he grabbed it and i was still holding onto it and he was like dragging me on the floor and i was like nooo! hahahaha and so today during lunch my other friend natalie was like sooo are you and cody going out? and we were like uhh no and she was like oh do you like love kristina? and he was like yea and i was like i love cody too...as a friend and he's like yea that. and then she was like ok tell me the truth do you think shes cute? and he's like yea and i was like like a friend right? and he was like oh yea and so yea lol am i sending him mixed signals? do you think he likes me? sorry if its long haha
