Your Partner Has Cheated — What to Do Now
The discovery is recent. You're in shock. What to do — and what to avoid — in the days that follow.
Reviewed by certified relationship advisors
You've just found out. Maybe an hour ago. Maybe three days ago and you still can't sleep. Your mind keeps circling — scenes you're imagining, words they said, the question with no answer: "How did I not see this coming?"
What follows isn't an action plan. It's a survival guide for the first few days — to help you avoid irreversible decisions made in the worst possible moment.
What you're feeling is normal
The shock, the nausea, the rage, the deep sadness, the urge to delete everything or know everything at once — all of it is a completely normal response to a real betrayal. Your nervous system has been through a trauma. Treat yourself with the same gentleness you'd show if you were physically hurt.
What not to do in the first 48 hours
Make a definitive decision about the relationship. Whether to stay or leave is a decision you will make — but not today. Not like this. Decisions made in the first 48 hours are frequently regretted, in either direction.
Confront the other person. Whether that's the affair partner, a mutual friend, a colleague — it won't give you what you're looking for. It'll most likely cause you more pain.
Post about it. What you put online stays online. In a few weeks or months, your situation may have shifted. Protect your privacy.
Ring everyone you know. Talking to one or two trusted people: yes. Broadcasting it: no.
What you can do
Ask for what you need right now. Space or company — both are valid. "I need a few hours on my own" is a legitimate request. So is "I need you not to leave tonight."
Find someone to talk to — a close friend, a therapist if you have one, the Samaritans (116 123) if you're struggling and it's the middle of the night.
Look after the basics. Eat something. Sleep if you can. Your body still has needs even when everything else has collapsed.

The questions that will come — and those that can wait
You'll want to know everything. How many times. How long. Whether it was better. These questions have limited value and unlimited capacity to hurt.
Some questions are useful: Was this a one-off or a relationship? Is it still going on? Do you both want to try to rebuild?
Some are better left alone: The physical details. The comparisons. The "why didn't you say no" directed at the other person.
What happens from here
The decision to stay or go comes later. After the shock. After a conversation where both of you can actually hear each other. After you've considered both options with at least a little calm.
You don't have to decide now.
If you're really struggling: The Samaritans are available 24 hours on 116 123. Relate (0300 100 1234) offer relationship counselling. Mind (0300 123 3393) can support you with your mental health in the aftermath.
What to remember:
- First 48 hours: survive, don't decide.
- Don't confront the other person, don't post online, don't make the decision.
- Talk to someone you trust. Sleep. Eat.
- Useful questions: one-off or relationship? Still ongoing? Do you both want to try?
- Stay or leave comes after the shock has passed.
