Answer:
I would never call the end of any relationship a "failed relationship"
Explanation:
Even though the relationship itself didn't work out whether that be with a friend significant other it always teaches you something. For example, if you into a relationship with a person and you saw slight red flags that turned out to be the reason you or them ended it now you know what to look out for. It even works in positive ways like if you liked the way they'd always ask if you ate now you know what you like or don't so no relationship is a "failed relationship" it's a learning experience
