I don't know what this is hahha please help! if you dont like the length just look at the start and end :)?

so my best friend.. hes been my best friend for 3 years now and when we first met we were like all texty texty and planned to sneak out and meet up and he took me to his formal but everyone now says that he would be like no i dont see her like that! but i dont know because i used to get angry when people talked **** about him liking me and expecting things from me (ual) so we used to have little arguments. now he's my best friend and our normal behaviour is to just play around poking eachother and annoying eachother on purpose he even squishes my face and talks all baby like being like you sho cute! and all my friends think he's completely and utterly in love with me; they all told me but at different times and i was like um no how ? and they said just the way he looks at me. but i never noticed these things until a few weeks ago. its crazy. i can't stop thinking about it, whats worse is he has a girlfriend now for like 6 months and i like im not gonna try and ruin it or anything but he seems so serious! and he still acts the same way, except lately he's been weirder around me. like i went to his place the other day and stayed till like 11pm! on a school night haaaaa and we were all playing a game ( his sister and sisters friend) and he dropped something and he was like "where did it go" reaching his hand in between my legs.. like not close to the leg if you get me hahaa and every time i got hyper i was holding his thigh and his usual reaction to anything me and and vag is like " eewww eewww!!" and my other friend said he overdoes it so it might be like a cover up? i don't know what to do. he's my best friend. i dont want to ruin it. i dont know how he feels. and it's really frustrating cause we cant go lke a day without seeing eachother and when we fight it lasts about ten minutes and then we go back to annoying eachother and playing around and he carries me around and everything hahah we get oOOooh alot but its always us being like NO and him being like EEWWWWWWWWW like a gay boy or something hahah but i really am stuck PLEASE HELP ME !
