Toxic relationships

IRIS Prévention
28 April 2027
A toxic relationship is not defined by a bad person: it is defined by a dynamic that systematically erodes my well-being, my self-esteem and my freedom.

Sometimes I come away from a conversation with someone feeling exhausted, diminished or confused, without really being able to explain why. Or finding myself constantly walking on eggshells, adapting each word to avoid the other's reaction. Or to excuse repeated behaviors that hurt me, convinced that “I’m the problem”. Toxic relationships are more common than you think, and their effects on mental health are documented and real. A study published in the Journal of Health and Social Behavior shows that poor quality relationships are more harmful to health than social isolation. Recognizing a toxic relationship, understanding why it is so difficult to move away from it, and finding the path to healthier connections is what we will explore together.

1. What is a toxic relationship, really?

A toxic relationship is not necessarily a relationship with a “bad person.” It is a relationship in which the relationship dynamic, the way two people interact, systematically erodes the well-being, self-esteem, freedom or security of one (or both) of them.

It can exist in all types of relationships: marital, family, friendly or professional. It is characterized not by occasional conflicts (normal in any relationship) but by recurring, persistent and unbalanced patterns.

The central criterion is simple: does this relationship leave me with more energy or less energy overall? Do I feel overall freer and better about myself after spending time with this person, or less?

2. The signs that should alert me

Here are the most frequently identified patterns in toxic relationships:

  • Systematic criticism and devaluation: my ideas, my decisions, my appearance, my abilities are regularly questioned or minimized. Over time, I internalize these criticisms and begin to doubt myself.
  • Control and surveillance: my choices, my associates, my schedule are regulated by the other. This control can be obvious or very subtle (guilt, emotional blackmail, manipulation).
  • Emotional instability and unpredictability: I never know what mood I will be dealing with. This unpredictability maintains a permanent state of alert and exhausting hypervigilance.
  • Progressive isolation: I see my friends, my family, my colleagues less and less. Sometimes on my own initiative, because the relationship absorbs all my energy or generates shame and secrecy.
  • Systematic imbalance: I give much more than I receive. My needs are never a priority. My boundaries are not respected.
  • Gaslighting: my perceptions, my emotions or my memory of events are regularly called into question. “That’s not what I said”, “you’re too sensitive”, “you’re making it up”. I end up doubting my own reality.

3. Why is it so hard to leave?

One of the most misunderstood questions when it comes to toxic relationships is: “but why stay?” » This question, often asked with kindness, ignores the real complexity of the situation.

Intermittent reinforcement: toxic relationships often alternate between difficult periods and moments of great gentleness or intense love (the “cycle of violence”). This unpredictable reinforcement is one of the most powerful attachment mechanisms; it creates a real emotional dependence, comparable to certain addiction mechanisms.

The erosion of self-esteem: after months or years of devaluation, I may come to believe that I do not deserve better, or that I am not capable of doing otherwise.Fear and dependence: fear of reprisals, economic dependence, fear of loneliness, fear of the unknown, these real and legitimate factors considerably complicate departure.

Shame and secrecy: recognizing that you are in a toxic relationship often involves social shame and a questioning of your own choices which is paralyzing.

4. The first steps to free yourself from it

Recognize and name what I am experiencing. The first step is to come out of denial or minimization. Keeping a journal of events and my feelings can help me see patterns more clearly, beyond the emotions of each interaction.

Talk to someone you trust. Breaking the isolation is essential. Sharing what I'm experiencing with a trusted person, friend, loved one, health professional, takes me out of the emotional confines of the toxic relationship and reconnects me to an external reality.

Reintroduce limits gradually. Setting boundaries in a toxic relationship is risky and difficult, but often revealing: the other person's reaction to a set boundary tells me a lot about the real nature of the relationship.

Get professional support. Psychotherapeutic support is valuable for understanding the dynamics at play, rebuilding self-esteem, and if necessary developing a safe exit plan. My general practitioner can refer me.

5. Towards nourishing relationships: rebuild afterwards

Breaking free from a toxic relationship doesn't mean all future relationships will be toxic. But this often requires rebuilding work, self-esteem, attachment patterns and the ability to recognize and set limits.

A healthy relationship is characterized by mutual respect, the freedom to be oneself, the ability to express one's needs and limits without retaliation, the balance between giving and receiving, and the opportunity to grow and flourish, together, but also separately.

💡 tips to remember

    • The central criterion of a toxic relationship: does this relationship leave me with more energy or less energy overall? Do I feel freer and better about myself afterwards, or less?
    • Difficulty leaving a toxic relationship is not a weakness: intermittent reinforcement (alternation of difficult moments and gentleness) creates real and documented emotional dependence.
    • Keeping a journal of events and feelings helps me see patterns clearly, beyond the emotions of each interaction. Recurrence is the key indicator.
    • Talking to someone you trust is the first break from isolation, often the hardest and most important. I am not alone, even if the toxic relationship made me believe it.
    • Psychotherapeutic support helps to understand the dynamics at play, rebuild self-esteem and develop a safe exit plan. In the event of violence: 3919 (Violences Femmes Info), available 24 hours a day.
