Trying to get a girl

I love this girl that I think knows that I love her and she is a grade older how can I be sure that she loves me back and if not how can I make it so she loves me

If she loves you she loves you. You can't force someone to love you or make them love you. If she knows that you are intrested in her and she is back she will approach you. Just wait and see what happens. Don't try and 'make' her love you because it just wont work. hope this helps,

Ask but you cannot make someone love you. Also I highly doubt you love her at all but whatever that still doesn't change anything. So yeah just go ask her one day out of the blue and see what she says.
