It wasn't a mistake. It was a learning experience. How much did you learn about yourself? About what you want for yourself? About what you need from others?

I'm only guessing that you learned quite a bit from this experience. We take something from every person we meet. Some people teach us about a TV show, some people teach us how to cook, some people teach us how to smile through adversity and some people teach us what we will and won't tolerate. What did you learn?

Go forward in life and find what makes you happy.
