background info: i go to an after school program after school. haha and if you don't pass your test there, you get a 30 minute detention afterwords. so i usually don't -_-. but there is a really really NICE T.A there who usually lets me go when he's not suppose to

. well the teacher usually knows that i don't pass so one day,after the corrected test was being passed out by the teacher. he said.. well, you have to go to detention. and then i asked the teacher if it was john T,A - ing in detention today. and he said yea i think and i said thats good, he'll let me go then haha. so the whole class was like, whooo he likes you and stuff and then i go uh no -_- and then the whole class goes.. then you like him. so when it was time for the t.a to come to ask whose in detention today, i was blushing HAHA only because it was embarassing, -_- and i don't like him, at least that time. well my classmate told him that ilike him

even tho i don't. and he's like oh okay..
on that same exact day, me and my friend went to a fast food place and saw him with his gf and it was all okay. but i guess 3 months later? which is now. i realized that i DO like him -________- how weird is that. the way he looks at me , the way he ALWAYS talk to me, and the way he helps me, makes me CAN'T stop thinking about him.
& i don't know what to do -_- some people say he likes me cuz he flirts with me and stuff. but ... i have no idea what to do.. should i tell him or what? help THANKS
