This is the part where a profile change from "in a relationship" to "single" would have sufficed. And to be clear, here is a list of things that are eras:

1. The Big Band Era
2. The Precambrian Era
3. The Elizabethan era

Things that are not eras:

1. That time in your life you were 'Sonia and Some Dude Forever'
2. Back when you used to play soccer.
3. Pants.

And as the submitter Matthew commented, "Abuse of the ellipsis is by far the most annoying status 'technique'." (Thanks, Matthew!)
