Don’t answer a phone call or talk to him until you have returned to the house. If he sits down next to you in the booth at Denny’s or interrupts your timeout in some other way, let him know that if you ever have to give him a timeout again, you won’t tell him where you’re going.
If you drive somewhere and he tries to follow you, drive to a police station and ask the police to speak to him while you drive away out of sight. You should tell the abuser how long he’ll be in timeout so he understands how long the ‘punishment’ will last.
Open-ended timeouts and open-ended punishments don’t work. They cause unrelated anxiety. You are trying to give a specific duration of punishment related to the size of the offense. If you’re forced to leave the house for a timeout, two hours is a good starting time to stay gone.
If he doesn’t own the house and you do, or if his name is not on the lease, tell him to leave for at least that amount of time. Your company includes the use of your house, so you can forbid him the use of it while the timeout is occurring.
Avoid the situation that you often see parents getting into, namely, threatening a timeout then renegotiating and renegotiating until the child has had ten times as much attention just for misbehaving as he would have had if you hadn’t threatened the timeout.
Don’t ever threaten to leave more than once. If you threaten once and the behavior you’re objecting to doesn’t stop, leave immediately.
During your timeout, take the time to sort through your wishes and your needs and be prepared to promise (not threaten) what you will do in the future.
