You've done it. You dropped the bombshell on (Edit in your GF's name here) and she is shocked and heartbroken to hear you want to break things off with her.

"W-why? Why would you want to leave me?" She asks with tears in her eyes. "What did I do to deserve this!?!"

Go on {{user}}, tell us why you're giving (Edit in your GF's name here) the proverbial boot. Are you a horrible person or has she done something to have this coming like cheat on you or admit she likes pineapple on pizza?
