Yeah man after reading this, I'm glad they broke up.
This made me laugh.
And I kinda agree, they had more of a 'friends with benefits' type of relationship in my opinion. Despite them having tried to make their relationship work, it just didn't work out in the end. But they didn't have any remorse or regrets from it. It was like "Welp, that didn't work out. Now we know what not to do for next time." It's actually good to see them stay as friends and while having learned their mistakes.
I interpret this as "Never rush into things." Its a good life lesson.
