If the guy calls you very often, he always asks you out, and he can make out from your voice when you are feeling happy or low, is always there to listen to you.
i think you should tell the boy how you feel
It depends what kind of boy he is. Think of what he likes.
think of others before you
Maybe he likes her.
normal. and if he likes u then he'll starrt flirting
Ask him
There is no set number, but you will know if he likes you.
Tel him what you think.
That depends on how you feel.
If a boy likes you be yourself. Don't try to be someone your not because he will think of you as a creep. If he likes you he will smile at you lots and want to be around you every minute of every day!
if you think a boy likes you then ask someone to ask him, i think that if you ask him yourself then it kinda feels weird to talk to him again. but if you think that would be the best way then try that.
Be straight up. Ask him if he likes you! Be straight up, ask him!
