The Cold Shoulder
There’s ghosting, and then there’s literally turning your chair around so that you can’t see the other person when they say hello. This might be the most awkward way to break up with somebody (for her too), although, if these stories prove anything it’s that people are always weirder than you think.

At least she could have said, “Hey I don’t think this is working out,” or something. Saying anything would have been better. This is a pretty harsh way to turn someone down by literally turning your back on them. Honestly, it might have been better to break up over text.
