It is vital that you discuss Time Outs with your partner. Before using Time-Outs, share with your partner how and why they work. Together you can review this page or cover the reading in Learning To Live Without Violence (pgs. 4-7).
Now leave your home for 1 hour. No longer and no shorter.
Return in one hour when you feel ready to listen.
Check in with your partner; if you both feel comfortable doing so, discuss what it was that made you angry. Otherwise schedule a more appropriate time to come back and discuss the issue.
If you can't take a Time Out when you don't need it, you probably won't take a Time Out when you do need it. Practice Time Outs are taken when you are not feeling angry. Your are practicing saying the words and walking away.
Tell your partner:
"This is a Practice Time Out: I am beginning to feel angry and need to take a time out. I will be back in 30 minutes."
Then leave for 30 minutes, return and check in.
