When a Toxic Person Comes Back: 6 Techniques to Protect Yourself Without Falling Back Into the Trap

When Ghosts from the Past Come Knocking

A WhatsApp message. A LinkedIn connection request. A dinner invite “as if nothing happened.” Sometimes all it takes is a small gesture for a toxic relationship from the past to resurface. An ex, an overbearing friend, a manipulative coworker… You thought you were finally free. And yet, here you are again, facing the same dilemma: Should I respond? And if so, how?

According to a study from the University of Michigan, toxic relationships can leave long-lasting emotional scars, affecting mental health, self-esteem, and decision-making abilities. That’s why it’s essential to protect yourself, without falling into aggression or withdrawal.

👁‍🗨 How to Recognize a Toxic Person

Before you act, let’s clarify. A toxic person isn’t necessarily “bad” in the absolute sense. But they are someone whose presence consistently has a negative impact on your emotional well-being, energy, or sense of safety.

Here are a few warning signs:

• They constantly make you doubt yourself.
• They regularly cross your boundaries.
• They come back when you’re feeling vulnerable.
• They use guilt or emotional blackmail.
• They leave you emotionally drained.

➡️ MindDay Tip: Use our emotion tracker to note how interactions with this person impact your mood. It can help you clearly see if the relationship is dragging you down.

🔒 6 Concrete Techniques to Avoid Falling Back

1. Welcome Your Emotions Without Judgment

When a toxic person comes back, you might feel panic, confusion, or even nostalgia. That’s totally normal.

🧘 Exercise: Take 5 minutes to name your emotions (anger, fear, guilt, excitement, etc.). What we name, we tame. It helps you regain control of the situation.

2. Avoid Impulsive Responses

In a panic, you might feel tempted to reply right away—to explain, defend yourself, or stay polite.

❌ Bad idea: responding quickly is usually driven by fear or nostalgia, not reflection.

✔️ Wait 24 hours. Write your response in your notes app. Let it sit. Then review it with a clear head.

3. Remind Yourself Why You Cut Contact

Toxic people often reappear at their best. They might seem to have changed. But deep behavioral patterns take time to shift.

📓 Take a moment to reflect on your past experiences. Write down 3 specific situations where this relationship hurt, manipulated, or drained you. Reading these will help reinforce your boundaries.

4. Use the "Calm No" Technique

We often believe we need to justify ourselves or get angry to say no. In reality, a calm, firm refusal is more effective.

💬 Example: “I’d rather not reconnect. Please respect my decision.”

Cognitive Behavioral Therapy (CBT) teaches us that assertiveness without aggression is a key driver of psychological well-being.

➡️ You can practice this in MindDay’s guided video sessions.

5. Visualize Your Future, Stronger Self

Toxic people often awaken an older version of you—the one who didn’t dare say no, felt “too nice,” or not good enough.

Try this visualization:

• Close your eyes.
• Picture yourself in 6 months—fulfilled, calm, surrounded by people who respect you.
• Imagine this “future you” facing the toxic person: how do they react?

This helps you make choices aligned with your present, not your past.

6. Seek Support If Needed

Dealing with a returning toxic person is emotionally exhausting. You don’t have to face it alone. A therapist, a trusted friend, or the MindDay app can help you set and maintain healthy boundaries.
