Difficulty: Moderately Challenging
Step1
See your girlfriend in person to do the breaking up. Only a face-to-face break up is appropriate under any circumstances. Sending a break up email, text message or voice mail message is never appropriate.
Step2
Think up how to approach the break up before it happens. Plan a few points to cover so that your girlfriend understands everything you are trying to communicate. Take notes if you think it will help you to remember, but never read the notes during the actual break up.
Step3
Break up in a private place so that your girlfriend is free to cry if she needs to and can express her anger without embarrassment. A break up is a hard thing even when both parties want it. There's no reason to make it harder by ending the relationship in a public place.
Step4
Communicate everything to your girlfriend that she needs to know about the break up. Stay away from cliches that don't help the process. Tell the truth out of respect to your soon to be ex-girlfriend. This will help her learn from the relationship and to move on from it.
Step5
Answer any questions your girlfriend has. If there aren't particularly hard feelings, you both might want to set up rules about a future friendship. If there are hard feelings, there still may be a few other things to settle. Any items left at each other's homes should be accounted for as well as any items owned jointly.
