The same way you know if anyone likes you. They talk to you, they smile at you, they are pleased to see you. They spend time with you when they could be doing something else.
I gess the same way you can tell if a normal girl likes you.
well if a girl is Bisexual then that means not only she likes men but woman also so i don't know if your a female or male but i doesn't really matter a bisexual girl can like you.
Same way you can tell if a straight man likes a girl. Usually they would admit to it, it act like they have a crush on that person
he will try to be mean to her because she does not whant the girl that he likes her.
You ask her!
You will know if u fancy a boy and a girl at the same time.
she will call u
She is probably a big flirt...ask her if she likes you..
If someone likes you they will spend time with you, laugh at your jokes, smile with you, talk to you, look at you when they could be doing something else. It doesn't matter who you are, you can always tell if someone likes you.
talk to her.get to know her ask about her sexuailty tell her yours and go from there
a way to know if he likes another girl is if he keeps looking at her and smiling also if he talks about her with his friends.
I think that the best thing to do is to tell him. Sure, he doesn't like you, but he deserves to know how you feel
