I think about her every day
Why do you think about her so much?
I'm in love with her, but she doesn't know it
It's not healthy to obsess over someone who doesn't know how you feel.  Let her know that you are interested, and it might lead somewhere.  Otherwise, you should move on.
I will make her fall in love with me.
The way to do that is by letting her know how you feel. You should tell her and then see what happens.
