This is the hardest page on the site to write honestly, because there is no right answer in the abstract. Some relationships should end and people stay too long; some relationships could be repaired and people leave too quickly. The two costs are not symmetric: leaving a workable relationship and leaving an unworkable one feel similar in week one and look very different five years later.

This page is for the version of this question most people actually have: not "should I leave?" — that one rarely has a clean answer — but "how do I think about this clearly?"

Distinguishing the kinds of "should I leave?"

The same sentence can mean very different things. A few rough categories:

Knowing which version of the question you are in shapes what comes next.

If you are in a crisis

The week after a major rupture is not when to make permanent decisions. The nervous system is in survival mode and clarity rarely lives there. Useful moves at this stage:

For affairs and serious breaches specifically, see rebuilding trust. The decision to try repair is not the same as the decision to stay forever; it is the decision to give the next several months a real shot.

Questions worth sitting with

Not "tests" — questions that, taken honestly, often produce more clarity than another argument:

Sit with these for weeks, not hours. Write them down. The honest answers usually point in a direction.

Real effort vs. theater

Couples often go through a period of "trying" before deciding. The trying that matters has a few features:

If you have done all of these honestly for several months and the relationship is still not somewhere you can live, that is information.

The reasons that look like good reasons but usually are not enough

The reasons that often are enough

If you decide to stay

Decide on purpose. "We are staying, and here is what we are going to actually do differently" is a different decision from "I guess we are still here." Couples who choose to stay after a real wobble often describe the relationship as steadier than before, but only if the choosing was active.

If you decide to leave

Decide on purpose here too. The cleanest endings are honest, kind, and prompt: said clearly, not stretched out for months of rehearsal. The kindest version is rarely the most comfortable one in the moment.

Practical points for the months that follow:

If your relationship involves physical violence, intimidation, or coercive control: please reach out to a domestic-violence support service in your country. Leaving an abusive relationship safely is its own process, and you do not have to figure it out alone.
