I like this boy he's younger than me and he likes my sister I asked him out but he said no I'm totally and completely in love with him I think he's sooooooooooo cute and peng I really want him to like me can you help me please tell me how I can get him to fall in love with me.:p

You can't make anyone fall in love with you. He knows you are interested, so play it cool and see what happens.

What age are you?

Try to let a little time pass and reevaluate this. Maybe time will change his views.

Hes not intereted. This seems nothing but a high school crush, an infactuation. Keep yourself away from him and busy. In time you will meet someone.

I am sorry to say also, you cannot make anyone love you, if you have no choice though, be fun, bubbly, flirting and enjoy any time you have with him.
