Robin: Where do you see yourself?
Ted: Honestly, in five years, I probably want to be married.
Robin: And I probably want to be in Argentina. [...] Or Tokyo, or Paris. Ted, I don't know where I'm gonna be in five years. And I don't want to know. I want my life to be an adventure.
Ted: ...we have an expiration date, don't we?
Alice and Bob are at a crossroads. Alice has recently come out and admitted she eventually wants to settle down, get married, and have kids, while Bob doesn't want to be tied down in life. So now they have a decision to make: they can either stay together a few more years and then break up, or they can break up now and avoid wasting their time. They choose the latter. It's not that they no longer love each other, but they both know that if one of them gets their way the other will be unhappy. And thus they part.
This trope has many different forms, but the gist is that two romantic partners break up because they both want different things out of life. Three variants are most common:
- Alice wants to eventually get married but Bob doesn't so they break up.
- Bob wants to have kids with his wife Alice but she doesn't, so they divorce.
- The above options overlap.
These types of breakups tend to be especially tragic since neither partner actually wants to part right now, but they both know it will be better in the long term.

- In Amazing Fantasy, MJ divorces Peter not because he wouldn't have a child with her (they have one Mayday Parker), but because she grew tired of worrying about him not dying on every superhero adventure and his inability to ignore his Chronic Hero Syndrome long enough to be a father and a husband. He's deeply regretful because of this and almost feels cursed with his insistence on Comes Great Responsibility.
- In the fourth and final story of ''The Anguis Series'', Beyond This Place, it is revealed that Cal and Nat had broken up due to the vastly different demands of their careers and lifestyle.

- In Spider-Man: Into the Spider-Verse, Peter B. Parker of Earth-616 got divorced from Mary Jane because she wanted kids and he had commitment issues.

- Reversed in the Sam Raimi Spider-Man Trilogy.

- In Little Women, their different ideas about their life is one reason why Jo refuses Laurie:
Jo: You'll get over this after a while, and find some lovely accomplished girl, who will adore you, and make a fine mistress for your fine house. I shouldn't. I'm homely and awkward and odd and old, and you'd be ashamed of me, and we should quarrel — we can't help it even now, you see — and I shouldn't like elegant society and you would, and you'd hate my scribbling, and I couldn't get on without it, and we should be unhappy, and wish we hadn't done it, and everything would be horrid!

Phoebe: But I don't think I can! It was okay to move in when I didn't know what was gonna happen, but I can't move in knowing nothing is ever gonna happen.
Mike: Can't you at least try living together? I mean, you might change your mind about marriage.
Phoebe: Are you gonna change yours?
Phoebe: Me neither. I...I think I need to be with someone who wants what I want.

When they start to conflict over how many children to have (she only wants one or two, he wants several), he also insists on working that out, and they agree to compromise.
