1. Accept what you can’t change and control what you can
When dealing with child custody issues you will by no means be able to change your co-parent. No matter how much they need to change (in your opinion), that work belongs to your ex.
What you can and must control are your own life and responses.
If you are co-parenting with a difficult ex, you know your buttons are likely to get pushed. You will require a steady temperament and resolved composure in order to maintain your dedication to great parenting.
2. Acknowledge the dynamic and how it plays out
How does the interaction with your ex go from zero to 90 in the course of a breath? Are there identifiable patterns to your communication? Do you have fears that get triggered? Are those fears based on reality and logic?
What can you do to disrupt an harmful dynamic and steer it in a direction that empowers and protects you?
Remember, the children and your integrity and sanity are non-negotiables. And the only person you can control is yourself.
3. Set new boundaries
Again, this is really about you and how you are going to engage (or not) with your ex.
Do not allow yourself to be baited. Take defensiveness and emotional reactions off the table. Set time parameters for communication, and stand by them.
Limit the means of communication. For example, you don’t text them but only use e-mail and a parenting portal. (Talking Parents is a free option for both avoiding disputes and documenting communication between co-parents.)
You may also want to consider blocking your ex from your social media.
It will be up to you to stand by your boundaries when your ex challenges your resolve.
4. Don’t respond immediately
So much of co-parenting with a difficult ex is about not engaging. Of course, you will have to engage on behalf of your children. But you do have the power and right to choose when and how you engage.
If your ex says or writes something that causes an immediate dump of adrenaline into your system, take a breath and step back. Do your “reacting” in your own mind or when you’re venting with a friend. Do your “responding” once you are calm.
And sleep on your response. Choose a doable ‘delay time’ for responding to anything other than emergencies. You’re not on-call for your ex.
5. Do not react to everything
Just because your co-parent pushes your buttons in order to lure you into engaging doesn’t mean you have to engage.
Stay focused on what co-parenting is about: parenting. It’s not about hashing out your unfinished marital discord or diminishing one another.
Respond to communication about the children. Let the rest go or add it to a happy hour vent session with a trusted friend.
