I've been trying to make someone fall out of love with me because I like someone else
Really? Why are you rejecting the person that is in love with you?
I want her to fall out of love with me so that I can be with another person
You are putting all the responsibility on the other person. You also have responsibility here and if you are with someone that you don't love, you should break off the relationship yourself and not push someone else to do it. That is cowardly.
I can't leave the person that I like to be with, I am confused and mad at myself!
This behavior sounds abusive. You need to figure out what you want before you hurt others being so selfish.
