2. “I never really liked you!”
“So you just forced yourself to date me? Why were we dating anyway?” Guys are appalled when a girl tries to deny their whole relationship by saying she never liked him in the first place. If you cut a guy deep like this, no amount of apologies will bring him back. In this case, it would be better to just say something over the top, like, “I hate you!”, which you can apologize for later.
