Is Your Relationship Healthy? 4 Behaviors to Watch For

By Debra Feinberg, LCSW, Robert Jenkins, LCSW (Reviewed by Senior Level Therapists)

In any partnership, it’s often the small, repeated actions that shape the health of your bond. Whether you are just starting or have been together for years, understanding what strengthens your connection versus what weakens it is essential. Sometimes, patterns develop that feel off, creating distance or tension where there used to be closeness. You might not even have a name for it, but you know something needs to change.

Healthy relationships are a source of support and joy. They make us feel seen and secure. However, certain behaviors, often called “toxic,” can creep in and slowly erode the trust, respect, and intimacy you’ve built. Recognizing these patterns is the first, most powerful step toward creating a partnership that truly nurtures you both.

This post will explore four common but damaging behaviors that can undermine a relationship. We will look at real-life examples to help you identify them and offer actionable steps to guide you back toward a healthier, more connected bond.

What Are Toxic Behaviors?

Toxic behaviors are actions or attitudes that cause emotional harm to a partner or the relationship itself. They can be subtle or overt, intentional or unintentional, but the result is the same: they create an environment of negativity, stress, and emotional distance.

Over time, these behaviors can lead to a complete breakdown in communication and trust. They don’t just affect the relationship; they can have a significant impact on your individual mental and emotional health, leading to anxiety, low self-esteem, and feelings of isolation.

1. The Quiet Damage of Passive-Aggression

Instead of addressing conflict directly, passive-aggression uses indirect ways to express negative feelings. It avoids open conversation, leaving the other person confused and hurt. It’s the difference between saying “I’m upset that you’re running late” and saying “Wow, nice of you to finally show up” with a sarcastic tone.

Real-life example:
Mark was frustrated that Sarah had been spending a lot of time with her friends. Instead of telling her he felt neglected, he started giving her the silent treatment after she came home. When she asked what was wrong, he would sigh and say, “Nothing, I’m fine,” while pointedly avoiding eye contact and making noise as he did chores. Sarah felt like she was walking on eggshells, unable to address an issue that Mark refused to name.

The long-term impact:
Passive-aggression makes genuine communication impossible. It breeds resentment and creates an atmosphere of uncertainty. The partner on the receiving end feels constantly on edge, and the person being passive-aggressive never has their needs truly met because they are never clearly stated.

Actionable Steps to Overcome It:

• For the person being passive-aggressive: Practice vulnerability. Before you react, pause and identify your real feeling. Is it anger? Hurt? Fear? Try expressing that directly using “I” statements, such as, “I feel lonely when you make plans without me.”
• For the person receiving it: Name the behavior without accusation. You can say, “I feel like there’s tension between us, and when you say you’re ‘fine,’ it doesn’t seem that way. Can we talk about what’s really going on?” This invites a more direct conversation.

2. The Slow Burn of Constant Criticism

While constructive feedback can be helpful, constant criticism wears a person down. This isn’t about bringing up a legitimate concern; it’s a pattern of nitpicking, fault-finding, and making a partner feel like they can never do anything right. It often focuses on a person’s character rather than their actions.

Real-life example:
Every time David tried to help around the house, Maria would follow behind him, re-doing the task. “You missed a spot,” she’d say about the counter. “Is that really how you’re going to load the dishwasher?” This extended to his personality, with comments like, “You’re just not a very thoughtful person, are you?” David eventually stopped trying to help, feeling defeated and inadequate.

The long-term impact:
Excessive criticism destroys self-esteem and creates a parent-child dynamic in the relationship. The criticized partner withdraws to protect themselves, leading to a loss of intimacy and affection. The criticizing partner often feels increasingly frustrated, creating a vicious cycle.

Actionable Steps to Overcome It:

• For the critic: Focus on appreciation. Make a conscious effort to notice and voice what your partner does right. When you have a complaint, use a “soft start-up.” Frame it as a need, not a defect: “I feel calmer when the kitchen is clean. Could we work together on tidying up after dinner?”
• For the criticized partner: Set a boundary. You can say, “It hurts me when you speak to me that way. I am open to hearing your concerns, but I need you to be kind.” This protects your self-worth and asks for a change in behavior.

3. The Suffocating Grip of Jealousy and Control

A little jealousy can be normal, but it becomes toxic when it turns into possessiveness and control. This behavior stems from insecurity and a deep-seated fear of abandonment. It manifests as monitoring a partner’s phone, questioning their friendships, limiting their social interactions, or making them feel guilty for having a life outside the relationship.

Real-life example:
When Lena started a new job, her partner, Chris, became increasingly controlling. He would text her constantly throughout the day, getting angry if she didn’t reply immediately. He made negative comments about her male coworkers and guilt-tripped her for attending after-work social events, saying, “I guess you’d rather be with them than with me.” Lena started to isolate herself to avoid a fight.

The long-term impact:
Controlling behavior erodes a person’s autonomy and sense of self. It fosters isolation and can be a precursor to more severe forms of emotional abuse. Trust becomes impossible because the relationship is built on suspicion, not freedom and respect.

Actionable Steps to Overcome It:

• For the jealous partner: Address your insecurity. This fear is yours to manage. Professional therapy can be incredibly helpful for understanding the root of your insecurity and building self-confidence.
• For the controlled partner: Re-establish your independence. Clearly and firmly state your right to have friends, privacy, and activities of your own. A healthy boundary sounds like, “I love you, and I also need friendships and interests outside of our relationship. I will not be sharing my passwords with you.”

4. The Unresolved Tension of Conflict Avoidance

Do you or your partner do anything to avoid a fight? Ignoring problems doesn’t make them disappear. In fact, avoiding conflict ensures that resentments simmer under the surface, only to explode later over something small and unrelated.

Real-life example:
Every time a difficult topic came up—finances, in-laws, intimacy—Alex would shut down. He’d get quiet, say “I don’t want to talk about this,” or physically leave the room. His partner, Sam, felt abandoned and silenced. The core issues never got resolved, creating a growing mountain of unspoken tension and frustration in their relationship.

The long-term impact:
When couples avoid conflict, they miss the opportunity for repair and growth. Emotional intimacy stagnates because difficult conversations are where you learn to navigate challenges as a team. This pattern leaves both partners feeling lonely and misunderstood.

Actionable Steps to Overcome It:

• For the avoider: Take small steps. Agree to talk about a difficult topic for just 15 minutes, with the option to take a break if you feel overwhelmed. Remind yourself that conflict is not a sign of failure, but a normal part of every relationship.
• For the partner who wants to engage: Create safety. Start the conversation gently. Reassure your partner that you are on the same team. You could say, “I know this is hard to talk about, but I want to understand your feelings so we can solve this together.”

You Can Build a Healthier Relationship

Recognizing these behaviors in your relationship—or in yourself—can be difficult and unsettling. Please know that it’s a sign of strength and self-awareness to even consider these questions. These patterns have no place in a loving partnership, but their presence doesn’t mean your relationship is doomed.

By addressing these behaviors with honesty and a commitment to change, you can build a stronger bond based on trust, open communication, and mutual respect.

If you are struggling to break these cycles on your own, seeking professional support can make all the difference. A therapist can provide a safe, neutral space to help you and your partner develop healthier ways of communicating and connecting. You don’t have to navigate this alone.

Frequently Asked Questions About Toxic Behaviors in Relationships

How do I know if my relationship has become toxic?
Look for patterns such as frequent criticism, feeling unsafe to express your emotions, being controlled or isolated, and avoiding important conversations out of fear. If interactions consistently leave you or your partner feeling hurt, unheard, or undervalued, it may point to toxic dynamics.

Can a relationship recover after toxic behaviors are identified?
Yes. Many couples are able to build healthier interactions once the patterns are recognized and addressed with openness and a willingness to change. Support from a counselor can help guide difficult conversations and encourage trust-building.

What if my partner doesn’t see their behavior as toxic?
Gently describe the impact the behavior has on you, using “I” statements such as, “I feel anxious when we avoid talking about important issues.” Suggest focusing on solutions together. If your partner is unwilling to acknowledge or work on the patterns, consider reaching out for professional support to help you decide on next steps.

When should I seek help from a therapist?
If you feel stuck, unsafe, or unsure about how to make positive changes, therapy can provide a confidential and non-judgmental space to get support. Couples often benefit from counseling when communication has broken down, when conflicts seem never-ending, or when trust is seriously damaged.

How can I bring up these concerns without starting a fight?
Choose a calm moment, express your desire to strengthen your relationship, and focus on your feelings and hopes rather than blame. For example, “I’d love for us to find healthier ways to handle disagreements so we both feel heard.” Compassion and curiosity go a long way.
