Stay at the home of one of your close friend who is single.
You can relax and ease your mind/calm down if you have a third party to talk to.
Major of the conflicts between couples can be cleared if they have the chance to calm & reflect. Staying at home sometimes lead to further deterioration of the situation.
Do consider this alternative if you conflict with your wife, and you belive there is no chance to find a quick & suitable solution.
Go to your parent's/brothers'/sisters' home is the 2nd best alternative because they usually incline to favour you when you discuss with them.
The not preferred alternative is to find a motel because you will have no one to talk to meaning that you have no third party's opinions.
The worst alternative is to stay at home. If this is the only immediately available alternative, let's say it is in the mid-nite, you still have to go out to avoid facing your wife. For example, you may visit a 7-11 downstair to buy youself a can of beer. Then take the chance to relax and review the case.
