How To Fix Toxic Behaviour in a Relationship

Toxic behaviour in a relationship can make the dynamics of the relationship unhealthy, leading to emotional stress and dissatisfaction for both partners. Controlling actions or emotional manipulation, toxic behaviours can slowly wear away trust and love in any relationship. What is toxic behaviour, and how can it be fixed?

Toxic behaviour in a relationship is considered the actions that can cause harm, either emotionally or mentally, to your partner. This connection would then be dysfunctional. The good news is that it can change, and self-awareness will have to put in some effort to get there. And the first step is being able to know the need for change.

Understanding Toxic Behaviour in Relationships

Toxic behaviour in a relationship refers to behaviour or attitudes that are damaging to the emotional and mental well-being of a partner. These can destroy trust, create anxiety, and even undermine happiness in a relationship. They include manipulations, constant criticisms, and disregard for each other.

The most important indicators of toxic behaviour in a relationship are:

  • Controlling or manipulative behaviour: One person seeks to control the other's decisions or cut them off from friends and family. Controlling behaviour and psychological abuse by a partner are recognised internationally as forms of intimate partner violence. [1]
  • Lack of respect and endless criticism: Belittling words damage their self-esteem as they feel unrespected and uncared for.
  • Verbal abuse: Using harsh words or insults or using emotional manipulation against your partner to control your partner or degrade the partner.
  • Blame shifting: Avoiding responsibility by blaming the partner for all the problems in the relationship.
  • Gaslighting: The partner is made to doubt the reality or perception of events to cause confusion and self-doubt.
  • Isolation: Separating the spouse from his friend and family system.
  • Excessive jealousy: Where one becomes obsessed with the behaviour of the spouse, accusing without cause.
  • Stonewalling and withdrawal: Lack of communication to solve conflicts while emotionally withdrawing when in conflict.

Such behaviour in relationships is often linked to unresolved personal issues or past trauma; for example, experiencing abuse in childhood or growing up in a family where abuse was accepted is commonly associated with abusive behaviour in adult relationships. [2] Breaking these patterns requires recognising the signs and dealing with the root causes. Recognising these toxic characteristics can be the first step towards healing and improving the relationship.

Warning Signs of a Toxic Relationship

  • Jealousy
  • Ignoring boundaries
  • Social isolation
  • Lack of support
  • Disrespect
  • Emotional abuse
  • Gaslighting
  • Poor communication
  • Controlling behaviour

Toxic Boyfriend Signs

This is some of the common signs that show if you are with a toxic boyfriend, such as:

  • Controlling behaviours

He tries to control what you wear, who you talk to, or where you go.

  • No trust

He constantly doubts you, checks your phone or accuses you of things without evidence. Reading a partner's messages, monitoring their location and accusing them of affairs are listed by the NHS among the signs of emotional abuse. [3]

  • Jealousy

He gets over-obsessive about you and makes you feel bad for spending time with others.

  • Emotional manipulation

He uses guilt, the silent treatment, or drama to control you or get his way.

  • Disrespect

He dismisses your boundaries, ignores your needs, or treats you poorly.

  • Mood swings

His emotions are unpredictable, making you feel like you're walking on eggshells.

  • Lack of support

He doesn't celebrate your successes and downplays your struggles.

  • Physical or vocal abuse

Every form of violence, whether bodily, vocal, or psychological, serves as a green flag.

How to Fix Toxic Behaviour in a Relationship: Practical Steps

Acknowledge and Understand Your Behaviour

The first step to fixing toxic behaviour in a relationship is to recognise that it exists. Self-awareness is important during this process. Ask yourself the following:

  • How do I contribute to our relationship problems?
  • Do my actions or words hurt my partner emotionally?

Reflecting on your behaviour gives you a starting point for change. Understanding how your actions affect your partner, and acknowledging your mistakes, helps you see what needs to improve.

Seek Professional Support

Therapy can greatly help in stopping unhealthy behaviour in relationships. A qualified professional provides a safe space for self-reflection and growth. Research reviews describe couple therapy as the widely accepted approach for reducing relationship distress and improving relationship quality. [4]

Jagruti Rehabilitation Centre offers relationship therapy to help people with toxic behaviour in their relationships find new ways of expressing themselves. It focuses on understanding the emotional roots of toxic behaviour and provides tools for building a healthier relationship.

Please note: where there is physical violence, threats or fear in a relationship, individual support and a safety plan should come before joint couples sessions.

Build Healthier Communication

To mend toxic behaviour in a relationship, you need to improve how you speak to your partner. Healthy communication is key to any relationship, and it means expressing yourself clearly while avoiding blame:

  • Use "I" statements rather than accusing statements (e.g. "I feel hurt when…").
  • Be a good listener and avoid interrupting your partner.
  • Avoid harsh words or criticism towards your partner, as these undermine trust.

Healthy communication can transform a relationship, encouraging understanding and empathy.

Practise Empathy and Patience

Empathy is key to understanding your partner's feelings and needs. When you practise empathy, you become more attuned to how your actions affect your partner emotionally. Patience is equally important, as changing toxic patterns takes time for both partners.

Being patient with yourself and your partner creates a supportive environment for mutual growth and healing.

Set Boundaries and Respect Them

To prevent unhealthy behaviour in relationships, both partners must establish boundaries and respect them. Boundaries include:

  • Respecting each other's personal space and alone time.
  • Avoiding hurtful words during disagreements.

Clear boundaries ensure both partners feel respected, which helps stop toxic patterns from returning.
