My big brother is in love with me!?

He probably does like you! thats not wierd though, even if he is like an older brothers. Sometimes boyfriends can be like older brothers. Yes that sounds wierd lol... but what i mean is, older brothers are over protective and boyfriends are to, cuz they care about you. He is probably over protective cuz he cares about you, in a boyfriend way. Like, he doesnt want you to get hurt (physically & emotionally) and he doesnt want u with other guys. Older brothers and boyfriends do these things, for different reasons. but the stuff u said he does is flirting! he deffenetly likes you. You never know, you might have always thought you loved him as a big brother, but maybe u do love him as a boy friend. Do you like him back? if so ask him out! its not like hes really your big brother, so it wouldnt be wierd at all. and if he didnt like you, he wouldnt make fun of you, because u guys are close, so he would just forget about it.
