In the Emails From Parents ("This Mom Has A Backbone"), you used the word "terminate." Could you elaborate on what you mean exactly by this term? Surely you're not telling us to abandon our kids.
When you "terminate the relationship," you're not saying to your child, "Hey ...I don't love you anymore, and I never want to see you again." Rather, you are sending a clear, verbal message that "as long as you choose to use abusive language and threats, I choose not to be around you." You could include the comment, "whenever you decide to stop using abusive language and threats, I'd love to spend time with you" (tough love that, in many cases, is equally tough for the parent).
In those cases where the child does not have the luxury of going to live with the other parent, you have to adopt a different approach obviously (which is discussed in the ebook).
I hope this clarifies,
