That depends entirely on how you frame the breakup.

And what most of do is insane.

We think of it as a failure.

About something that by design (monogamy, less true now) we will only ever get right one time.

Thinking about breakups as a failure is incongruous to the reality of what romantic relationships are.

Most of that thinking comes from religion. Even if we ourselves atent religious, the idea stems from religions, particularly ones that promote monogamy as a substitute for your relationship with the divine.

Once you realize that breaking up is not a failure, but a success because one or both of you realized you were not or were no longer right for the other, that hit to your self esteem doesn't happen like under the current paradigm.

Yes,. it still hurts. Yes, you're still sad and will be some depressed.

But it's not a gut punch to your ego like it is when you believe that your purpose on this Earth is to get married and have babies or you believe your manhood is not alidates without having been chosen.

You'll also be less likely to drag your feet ending things when you know you need to because you don't want to be "the bad guy/gal" or hand around for nefarious reasons that just make the inevitable end worse than it need be. You won't need to.

You'll also drift toward ending things more respectfully and humanely for yourself and you SO.

You've got psychological freedom most of your peers don't.
