If you haven’t had a relationship or breakup, what was the biggest or best lesson you learned from others’ relationships/breakups?

My answer: In my first real and serious relationship/breakup, I learned that I need to have boundaries and that I cannot fix people or a relationship that simply can’t be fixed. I struggled with saying “no” and always putting in too much effort for something or someone that didn't do the same. This lesson helped me navigate through my current relationship with ease.
