How to know when to stay and when to leave

“The question isn't 'am I unhappy.' It's 'is this fixable, and is anyone actually trying to fix it.'”

Staying or leaving should be decided by whether the situation is fixable and whether you're both willing to do the fixing — not by how uncomfortable the current moment feels.

Most people either leave too fast out of discomfort or stay too long out of sunk cost — both mistakes come from skipping the diagnosis.

What nobody tells you

  • Sunk cost — years invested, effort spent — feels like a reason to stay but is actually irrelevant to whether staying is a good idea going forward.
  • The discomfort of leaving and the discomfort of a situation that needs to end feel identical from the inside — this is why the decision needs external structure, not just a feeling check.
  • Many people leave the wrong thing first — quitting the job when the real problem is the manager, ending the relationship when the real problem is an unaddressed pattern that would follow them.

The basics

  • A situation is fixable when the problem is specific and addressable (a skill, a habit, a misunderstanding) rather than a fundamental mismatch in values or capacity.
  • Fixability requires two things: the problem must be solvable in principle, and the people involved must be actually willing to do the work, not just say they are.
  • Chronic unhappiness with no attempted fix and chronic unhappiness after a genuine, sustained fix attempt are completely different situations, even if they feel the same day to day.

The framework

Fixable and willing

Cross two questions to get a clear read: is the problem fixable in principle, and are the people involved willing to actually do the fixing.

  1. 01

    Fixable + willing: stay and do the work — this is the situation most worth investing in.

  2. 02

    Fixable + unwilling: the problem isn't the problem, it's the refusal to address it — this usually means leave, because willingness rarely appears without leverage.

  3. 03

    Not fixable, regardless of willingness: leave, with compassion but without waiting for a fix that structurally can't happen.

The playbook

0/7

The conversation — what to actually say

Deciding whether to stay in a struggling relationship

“I need us to actually try changing X for real, with both of us doing something differently, for the next few months — not just talk about it.”

Deciding whether to leave a job

“I've raised this specific problem twice and nothing's changed. I'm going to give it until [date], and then I need to move on if it hasn't.”

The mistakes — what people get wrong

  • Confusing 'this is hard right now' with 'this is unfixable' — discomfort during a real fix attempt is normal, not proof it's failing.
  • Staying because leaving feels like admitting the time already invested was wasted.
  • Leaving impulsively during a bad week instead of after a genuine, time-bound fix attempt.
  • Waiting indefinitely for willingness to appear on its own, without ever naming the specific ask.

Ask yourself

  • Is the actual problem specific and fixable, or is it a fundamental mismatch dressed up as a fixable issue?
  • Has this actually been addressed with changed behavior, or just discussed?
  • If a friend described this exact situation to me, what would I tell them to do?
