To tell if someone likes you...well they talk to you a lot, call you pretty or tell you they like your hair or outfit. Come to your locker whenever your there or is waiting for you there. Sits by you at lunch. H and his friends giggle and he blushes around you. If he tries to act funny or does dumb thing when he's around you! Well that's mostly young or preteen love! This would also be the same for a girl who likes a boy.
if he stares at you and tell to someone he likes me or tell me he likes me
Blondies aren't any different than other people. If you can tell when someone else likes you then you can tell when the blondie likes you
you can tell by their face.
tell them to get over you and date someone else.
If u find a change in someone's behaviour
Tell him
they'll flirt with you
Ask them or failing that waterboarding
Ask her.
Then tell that person if she likes you or just leave as is
you tell someone who he likes and then you tell them that he was talkin about her
get with another lad to try and make your crush jealous if it doesn't work then he likes someone else or get a friend to ask him if he likes someone and if he does tell your friend to ask him who he likes. if he doesn't like you then move on you can find somebody better then him, somebody that actually loves you.
