Infidelity

They say they love someone. They say they care about someone...

But when they start getting in arguments and fights, one or the other will turn to a
'friend' and as it happened in The Game, that one ends up sleeping with that
so-called friend because they fought and wanted comfort since the other is away.

Then that same person realizes just how much they really love the other, how much
they really care about the other.

The one who got betrayed gets angry after finding out. They fight some more. Then
that person feels stupid for misunderstanding what happened, without really knowing
what happened.

Sounds like an outtawack cycle to me.
