Finding out your partner cheated can feel like your world has been turned upside down.
The hurt, anger, and confusion can stick around, sometimes turning into something called Post-Infidelity Stress Disorder (PISD).
It is not just a catchy phrase—it is a real, heavy experience that can leave you feeling lost.
However, here is the good news: you can heal.
We are here to walk you through practical, down-to-earth steps to overcome PISD, rebuild your confidence, and find peace again.
Let us dive in with hope and honesty.
What Is Post-Infidelity Stress Disorder?
PISD is a term psychologists like Dr. Dennis Ortman use to describe the emotional rollercoaster after Infidelity.
It is not an official diagnosis, but it feels a lot like trauma. You might deal with:
- Flashbacks of the betrayal that hit out of nowhere
- Constantly checking your partner’s phone or emails
- Feeling numb or struggling to trust anyone
- Anxiety, sadness, or doubting your worth
These feelings can hang on for months, even years, if you do not address them.
Knowing what PISD looks like is the first step to taking back control.
7 Practical Steps to Heal from PISD
Healing is not a straight line, but every small step counts.
Here is a roadmap to help you move forward, with tips you can use today.
1. Let Yourself Feel the Hurt
It is okay to feel shattered. Trying to “just move on” can make things worse.
Grab a notebook and write what is swirling in your head—anger, sadness, or guilt.
Therapist Esther Perel says naming your emotions helps you process them without letting them take over.
Try setting aside 10 minutes daily to journal; it is like giving your heart a safe breathing space.
2. Find a Therapist You Click With
A good therapist can be your guide through this storm.
Look for someone who specializes in trauma or relationships—therapies like Cognitive Behavioral Therapy (CBT) or Eye Movement Desensitization and Reprocessing (EMDR) are fantastic for PISD.
Not sure where to start?
Platforms like BetterHelp or Psychology Today let you filter for therapists who offer virtual or in-person sessions.
If therapy feels pricey, check out low-cost options through Open Path Collective.
3. Create Clear Boundaries
Boundaries are your lifeline, whether you stay with your partner or solo.
If you are rebuilding, talk openly about what makes you feel safe, like sharing passwords or scheduling check-ins.
Dr. John Gottman, a relationship guru, says consistent boundaries build trust brick by brick.
If you are moving on, set boundaries with yourself, like limiting contact with your ex, to protect your peace.
4. Make Self-Care Your Priority
Betrayal can make you feel small, so do things that remind you you are enough.
Take a walk, try yoga, or cook your favorite meal.
Research shows 20 minutes of daily movement can reduce stress by 30%.
Lean on friends who make you laugh, or join a hobby group—maybe a book club or painting class.
Small acts of self-love add up, and you deserve them.
5. Rebuild Trust at Your Own Pace
If you stay with your partner, trust takes time and effort.
Be honest about what you need, and ask them to show up consistently—maybe through open conversations or couples therapy.
If you are healing alone, focus on trusting yourself.
Remind yourself of times you made wise choices or felt strong.
Trust grows slowly, but it is worth the wait.
6. Push Back on Negative Thoughts
PISD can trick you into thinking “I am not lovable” or “I will always be betrayed.
Fight those thoughts with facts.
Have you been a great friend or partner before?
Are there people who value you?
Try a CBT trick: write down a negative thought, then list three things that prove it wrong. It is like giving your brain a reality check.
7. Forgive on Your Terms
Forgiveness is not about letting your partner off the hook—it is about freeing yourself from resentment.
It might take months or years, and that is okay.
Studies from the Greater Good Science Center show that forgiveness can lower anxiety and boost your mood.
Start small: maybe wish them well in your heart, even if you are not ready to say it out loud.
Things to Watch Out For
As you heal, steer clear of these common traps:
- Pushing Yourself Too Fast: Healing is not a race. Give yourself grace if you are still hurting months later.
- Getting Stuck on “Why”: Obsessing over details of the affair can keep you trapped. Focus on what you can control now.
- Shutting People Out: Isolation feeds pain. Join a support group, like Surviving Infidelity’s online forums, or talk to a trusted friend.
Fun Fact
