How about I ask my wife to give me some time after our arguments?
That depends. Why do you need time from your wife?
She has some violent episodes which scares the shit out of me, I just want to take some time out.
That is a smart decision. Cooling off after a fight is smart, you do not want to stay longer than necessary and have more fighting.
It is smart. I'm a man with a plan.
I hope it goes well. Maybe the time to cool off after the fight will help her out too.
