When he looks at you he will get a rock on (boner) and smile like a creep.
he smiles at you, copies you
You don't.
You have to trust your instincts.
ask him...
If you wana know if he loves you so its in his kiss...thats where it is
If another girl loves another boy you can encourage them to speak. This well help them get to know each other better.
You can tell by how they act around you. If a boy calls you fit, ignore it, if they call you beautiful everyday, believe it! Only you know if a boy loves you.
If a boy lets you make your own decisions, listens to you when you are talking, and doesn't want you to change, he loves you just the way you are.
You can flirt a little and see what his reactions are.
If you don't know him the he doesn't know you well enough to love you.
first confirm that she takes interest in talking to that boy then the girl starts sharing her personal matters with him and it means that she loves that boy...
there are a lot of ways to tell... when he looks at you and his eyes get soft and his face turns mellow... he loves you.
