When a guy likes you they will often:
Smile at you
Look at you often
Push you
Call you names
Find reasons to talk to you.
Most of these things guys will do if they are into you.
If he pushes you in the dirt. or pulls your hair, or tries to make you follow him behind the toilets.
You can tell that a boy likes you if he looks at you a lot or he will send you a note sating that he likes you
you know if a boy likes if he gets nervous when he is around you, stumbles alot when he sees you, and he is always finding an excuse to talk to you.
Well he would probably pay attention to you accept for people that are bad boys they will probably be mean to you. And he will ask you if you like him OR he will say i know you like me or something like that.
when he does anything to talk to you
Ask him
He talks to you.
if he farts on your face
The best way to know is to ask him.
He likes you that is what is important. it doesn't matter who else knows you.
Ask him.
get to know him!
how you will know if a boy really likes you he will act all shy around you and he will blush sometimes. and when you talk to him he will not know what to say.! fingers crossed that he likes you honey!
