You don't
You can't make someone NOT hate you. Just ignore her and get on with your life.
you give her money
ask her what you did for her to hate you then try to make up for it
You can never make someone hate a group. Just give your cousin another girl group to think about.
What did you do in the first place to make her hate you? I am a girl so I know how to get a girl back. Just rub her feet.
Not really i guess, you'd probably just make them break up and they'll hate you forever (especially the girl)
Do not try to make someone hate someone else. They will just both end up hating you.
you make a girl jealous and the girl will hate her boyfriend and follow you as her boyfriend and listen to that song Justin bieber one time
