The first step toward setting healthy boundaries is assessing the problematic behavior on both sides. If your ex-wife calls too often, wants to make social dates that you don’t want, and places emotional burdens on you in ways that you feel are inappropriate now that you’re divorced, she might be crossing your boundaries. Consider the behaviors that allow her to cross those boundaries, says the counseling program of Johnson State College. If you give in to her requests every time even though you don’t want to, you need to address unhealthy behavior of your own.

Healthy, generous people set boundaries so that they can have a separation between themselves and other people, and ultimately give more to the people who matter to them, according to the counseling program. Setting boundaries doesn’t make you a mean or unfeeling person, despite what your ex-wife might say. Try putting it simply. You can say something like: “Now that we’re divorced, you may not continue to call me in the middle of the night unless one of the kids has an emergency.”

Reinforcing boundaries requires maintaining consistent behavior and consequences when your ex-wife crosses your personal boundaries. You can explain your consequence before, for example, “If you call me in the middle of the night and it turns out not to be an emergency, I will end the phone call immediately.” Then, if your ex-wife continues to cross your boundary line, implement the consequence.

If you and your ex-wife are co-parenting children, maintain civil contact with her. Set boundaries by focusing on your relationship as co-parents only, recommends marriage and family therapist Ron Deal. Deal suggests setting up a regular meeting in which you discuss the kids and your parenting strategies, and redirecting the conversation back to parenting if she tries to bring up other subjects. Don’t give in to manipulation; ask her to leave the kids out of your personal problems, says Deal.
