Face to face, and tell them bluntly.

In my vast experience of *ahem* one break up when I was the very mature age of 15...I sent him an email.
Nowadays, if I were to break up with someone I'd do it face to face, but back in the day...lol
To be fair, I was afraid to do it face to face because he had intense anger control issues and he didn't have a phone or FB so we only communicated outside of school via email.
*face palm* it was not the greatest way to do it though lol. My mom called his mom and apologized for my behavior lol
The way I broke up with him was unacceptable. That and texting. I would maybe understand a phone call but face to face is the stand up way to do it.
