It's like a relationship you had, say, in your school days. You both matured together, great partnership, things were looking up, bright future ahead.
Suddenly, WHAM! Some crazy incident throws everything into question. Some third party enters the scene and throws everything out of whack.
You break up. It's messy. Everyone does and says rotten things.
Later, you realize how awesome things used to be. You see the other party isn't as happy or well-off as they used to be, and you could say the same for yourself.
You want to get back together. But how? Who makes the first move? What do you say?
It's all very Splendor In The Grass right now.
