How to Heal After a Breakup: An ACT Therapy Approach
Why can’t I stop thinking about my ex?
After a breakup, the mind tries to solve the loss. It replays conversations, searches for the moment things went wrong, and asks “what could I have done differently?”
Recently, a client came to me struggling with exactly this. He couldn’t stop thinking about the person, and the more he tried to push the thoughts away, the louder they got. This is common. Trying to suppress painful thoughts usually keeps them in focus, and it leaves you exhausted.
What is ACT, and why use it for heartbreak?
Acceptance and Commitment Therapy (ACT) is an evidence-based form of psychotherapy. It doesn’t try to remove difficult emotions. It helps you change your relationship with them so they stop running your life.
With this client, we didn’t push memories away or tell him to “just move on.” We worked on three things.
1. Acceptance: how do you make room for the hurt?
Acceptance doesn’t mean liking the pain or giving up. It means letting the hurt be there without spending all your energy fighting it. Grief after a breakup is a natural response to losing something that mattered. When you stop wrestling with it, you free up energy for the rest of your life.
2. Defusion: is “I’ll never be happy again” true?
Defusion means noticing that a thought is a thought, not a fact. A thought like “I’ll never be happy again” feels completely true when you’re in pain, but it’s your mind reacting to a loss. Some simple ways to practise this:
- Add a prefix: “I’m having the thought that I’ll never be happy again.”
- Name the pattern: “There’s the replaying story again.”
- Notice the thought without arguing with it, and then return to what you were doing.
The thought may still appear. What changes is how much power it has over you.
3. Values and commitment: what matters beyond the relationship?
This is where healing turns into action. We asked what mattered to him outside this relationship: friendship, health, work, family, creativity, being a good son or brother. Then we committed to small, consistent actions that reflected those values. In practice, that meant:
- Rebuilding his daily routine
- Reconnecting with people
- Returning to activities he had gradually stopped doing
Do you have to feel better before you start living again?
No, and this is the core idea of ACT. The aim was never to wait until he felt better. It was to take meaningful steps even while dealing with difficult emotions. Often the feeling of being “okay” follows the action, not the other way round.
Where can you start this week?
- Pick one value (for example, connection or health).
- Choose one small action you can do in 10 minutes, like a walk or a call with a friend.
- Do it with the pain present, without waiting for it to leave.
- Repeat on most days, and let the routine rebuild gradually.
Frequently asked questions
There’s no fixed timeline. It varies with the relationship, the circumstances and the support you have. Healing is usually gradual, and small consistent steps tend to help more than waiting for the feeling to pass.
Yes. Replaying and “what if” thinking are common ways the mind tries to make sense of a loss. If it takes over your day, therapy can help.
ACT is widely used for emotional distress, and its focus on acceptance, defusion and values-based action suits the thoughts and feelings that follow a breakup. How well it works varies from person to person, and a therapist can tell you whether it fits your situation.
It’s a technique for seeing thoughts as passing mental events rather than facts, so they have less hold on your behaviour.
It depends on your situation. A counsellor can help you decide what’s right for you, based on your values and wellbeing.
