9. Reminds me of a Buddhist expression

"Do not let the actions of others destroy your inner peace". Its a principle I live by. For example, obnoxious drivers honking and tailgating me because I'm going the speed limit have no effect on me. Just the opposite. My lack of reaction makes them stop, and its effortless.

Jealousy of the other parent goes against that rule. As a child of divorce, the best thing a parent can do is focus on the child, and eliminate all negative thoughts related to the other parent. That relationship should have no bearing on yours. A child wants to get along with both.
