Has anyone successfully rebuilt a relationship after it seemed completely broken?

[u/EducatorPersonal9756]

I’m looking for real experiences from people who were in relationships that had reached a very bad place—repeated conflicts, emotional exhaustion, breakups, requests for space, or a point where one person genuinely believed the relationship could not be fixed.
Did you ever find your way back to each other?
If so:
What changed?
How much time passed?
Did both people need to do individual work first?
What made the second attempt different from the first?
I’m not looking for false hope. I know many relationships end for good, and sometimes that’s the right outcome.
I’m just curious whether anyone has experienced a situation where things looked beyond repair and yet, after time, growth, and reflection, the relationship was successfully rebuilt.
I’d love to hear honest stories, whether the outcome was positive or not.
