I have a way to really fuck with your relationship, and I don't have to do anything. I can guarantee this will turn it upside down, cause fights, make your wife or girlfriend question everything, and hurt her self esteem. I want you to stop fucking her. Refuse to have sex with her. Even if you don't have sex often, she wants it occasionally. Deny her. Dont touch her. She'll start to feel insecure and paranoid. Stop fucking her so I can watch your relationship fall apart.
