The relationship 'break'

What do you think about couples who go on a "break"?

You know, a split that includes a possibility they will get back together.

This college student writes how she and her boyfriend agreed to go on a "break" while she studies abroad over the summer. During that time, they've agreed it's OK to hook up with other people. She concludes:

We have discussed getting back together after I get back, but nothing is set in stone. We know that we’re young and that we have a long way to go before either of us considers settling, so, to be a little cliche about it, whatever happens, happens.

I think this is a recipe for disaster.

These situations always end up the same way. At the start, both partners talk about how wonderful the setup is and how it's great they're not jealous people.

Then, a couple weeks in, one person is pining away for the old relationship while the other has completely moved on.

The term "break" is simply an attempt to lessen the emotional severity of a breakup. Its attempt at leaving doors open is nothing but a vehicle for false hope.
