Mine happened over the phone back in 2012. One of the best decisions I've made was to break up with her. We were arguing about something (no idea about what, anymore) and I angrily shouted (in ptbr) "You don't need to call me anymore, ever again, it's over for us! Good bye!" - She was very angry at me and tried to call me back several times, I turned off my cell phone and disconnected the cord of the home phone. Since those weren't working, she called my mom, to which I replied "Whatever you have to say, I don't want to hear.", finishing the call without letting her speak.

The relief I felt then was HUGE.
