Is there any spell I can do by saying upon truth?

English is not my first language, so please bear with me.

I was friends with this one girl and I loved her so much. Everything I've done for her were all genuine that I can swear on my life. But now she turned around and said she doesn't care about me. She only cares about herself and said hurtful things. So yea, now I resent her and I want her to not have what she wants the most. Can anyone tell me what spell I can do?
