pay attention to how he acts around you compared to other girls. If he teases you more or talks to more or stares at you with dreamy eyes - he probobly at least is interested in you. Or maybe if you don't want to wait - ask him out! then your sure to find out!
he smiles at you, copies you
Walk away. If he loves you he will try to get you back. If he is playing you he will move on to the next girl without a thought.
You have to trust your instincts.
You don't.
To know if he loves you back. Read the signs of his body does he act like that as well. Look into his eyes does he look like he loves you.

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.
