What you feel after discovering infidelity can go beyond sadness or anger. Some people stop sleeping, barely eat, or are overwhelmed by images they cannot stop. That is not an exaggeration. It has a name: relational trauma, also known as betrayal trauma. And yes, what you feel is normal.
What is betrayal trauma and why is that a different word to ‘crisis’?
Betrayal trauma occurs when someone central to your safety destroys that very safety. That is different from an argument or a difficult period. The foundation upon which you built daily life turned out to be false. Your brain responds to this as it does to any serious threat: with alarm reactions designed to protect you.
The term ‘relational trauma’ or ‘betrayal trauma’ is used by researchers and therapists to describe precisely this. Not a diagnostic label, but an acknowledgement that the reaction is proportional to what has happened. They are not signs of weakness. They are signs that you were genuinely connected.
How does someone recognise trauma after infidelity in themselves?
Trauma following infidelity can manifest in several ways. In my practice, I often see that people do not recognise themselves in the weeks following the discovery. The reactions vary, but a number of patterns keep recurring.
Intrusive thoughts and images
Images of what happened force themselves upon you uninvited. During a meeting, in the shower, in the middle of the night. You cannot put them out of your mind, no matter how hard you try. In the blog How to deal with the images in your head after infidelity states more about why this happens and what does help.
Physical reactions that surprise you
Palpitations, nausea, a fuzzy head, or alternatively a kind of numbness. The body registers the betrayal before the mind can process it. Sleeping badly, eating little or conversely overeating, not being able to sit still. These are not psychosomatic symptoms born of powerlessness. This is how the nervous system reacts to a shock.
Hypervigilance
You are checking your partner's phone. You listen differently to sentences that used to be neutral. With every message, you wonder what lies behind it. That constant scanning for danger is exhausting. And it is a classic feature of betrayal trauma: the safety system is switched on, even when there is no immediate danger at that moment.
Functioning while everything inside is on high alert
A pattern that I find very recognisable in my practice, especially among entrepreneurs and professionals: on the outside, everything just works. Meetings are led, clients are helped, children are picked up. No person sees a thing. But on the inside, the chaos is complete. Functioning does not mean that things are going well. That distinction is important, because making it is the first step towards honestly seeing what you need.
When is professional help needed?
If the reactions persist, become more intense, or if you feel you are losing control of yourself, it is wise to seek professional help. A psychologist or trauma therapist is then the recommended path. That is not a failure. That is recognising what is going on.
Coaching focuses on the period when you want to regain control: over your thoughts, your communication, your choices. Not on the diagnosis or treatment of trauma, but on the steps you can take when the acute alarm is a little less loud. If you are currently in the middle of the first few days, please first read what helps and does not help in the first 48 hours.
What does this mean for the recovery of your relationship or yourself?
Infidelity trauma has no fixed timeline. The question ‘when will I be over this’ is understandable, but cannot be easily answered. What can be said is: acknowledging what is there, without dramatising or trivialising it, provides space. Space to feel what you feel, and then to decide what you want.
The sequence is not self-evident. Many people try to make the decision about staying or leaving right in the middle of the most intense phase. That is too early. Recovery, in whichever direction, begins with stability. With understanding what is going on inside you. With knowing that what you are feeling has a name and a reason.
At Reconnect Coaching, Petra Wijen works with the Affair Recovery Programme, aimed at people who are right in the middle of this phase and want to regain control step by step. Starting does not require a major decision. An initial introductory chat is enough to see if this is a good fit.
Veelgestelde vragen
Is it normal to become physically ill after the discovery of infidelity?
Yes. The body responds to emotional shock in the same way as to physical danger. Nausea, sleep problems, heart palpitations and a feeling of numbness are well-known physical reactions following betrayal trauma. If symptoms persist or worsen, it is advisable to also consult a doctor or psychologist.
What is the difference between grief after infidelity and trauma after infidelity?
Grief is an emotion that comes and goes in waves. Trauma manifests differently: in intrusive images, hypervigilance, physical reactions and a sense of constant alarm. With trauma, the nervous system is structurally switched on. That requires a different approach than grief processing alone.
Can I just keep working while this is processing?
Many people do that, and sometimes structure is even temporarily helpful. But functioning at work does not mean that the processing happens by itself. In my practice, I often see people working on for months while the internal crisis continues unabated. At some point, that takes its toll.
Do I have to decide right now whether to stay with my partner?
No. In the most intense phase of betrayal trauma, a well-considered decision is barely possible. Stabilise first. Understand what is going on inside you. The choice to stay or leave can be made later, with more calm and perspective.
Does coaching help with trauma after cheating, or do I need therapy?
That depends on the severity and duration of the symptoms. For persistent trauma symptoms, a psychologist or trauma therapist is the appropriate help. Coaching at Reconnect is aimed at people who are stable enough to take steps: gaining a grip on thoughts, communication, and the direction they want to take.
