Do not go back. Ever!

Learnt my lesson.

When you think they cannot become crueler or more ridiculously outrageous in the sense of making up arguments out of thin air!

You can be the calmest, deflect and say for example "everything is ok, nobody is arguing"

It really does not matter, they WILL create an argument out of nowhere, whilst their eyes are gleaming and they do not give a fuck about you at all.

DO NOT GO BACK. THEY DESTROY EVERYTHING
