The worst punishment you can give someone you love is your silence. When couples fight, they may shout at each other, cry, storm off to another room to find space, or even take a day or two to cool off before speaking to each other again. And then there’s the “silent treatment.”

You disappoint your partner in some way, and rather than responding, they shut down. You call ten times, but they won’t answer. You send lengthy texts, yet get nothing in response. You approach them face-to-face, attempting to speak with them, and still they won’t acknowledge that you exist.

This isn’t about needing time to work through intense emotions or to sort out thoughts, because that’s normally conveyed. It’s about watching your partner suffer, knowing they are hurting and feeling a sense of control over them. That’s where silent treatment crosses the line into unhealthy relational behavior.

Here are two ways to deal with silent treatment before it destroys your relationship.

1. Acknowledge The Manipulation

Silent treatment tends to fly under the radar as “harmless,” and a lot of people catch themselves excusing their partner’s behavior. They may tell themselves things like:

• “They were just angry with me because I did something wrong. It’s not their fault.”

• “That’s how they show anger. They’ve always been that way.”

• “They were hurting too; I don’t blame them.”

A classic study published in Group Processes & Intergroup Relations found that silent treatment is seen as primarily punitive and threatens four core psychological needs: sense of belonging, self-esteem, sense of control and meaningful existence.

The researchers also noted that although the sense of belonging of the person giving the silent treatment was diminished, their perceived control over the other person was reinforced.

It’s important to distinguish silence used to process emotions from silence used to manipulate. Some people go quiet because they feel overwhelmed, unsafe expressing their feelings or lack the skills to do so. Constructive silence happens when someone communicates that they need space to gather their thoughts and calm down before re-engaging.

Silent treatment, however, is unstable and unpredictable. The other person may ignore you completely, even when there are others around. This action may push you into panic mode, wondering what you did wrong or worrying that this silence is signaling a breakup. The ambiguity makes things much worse.

In some cases, the silent treatment is often used as a tool to gaslight the other partner into feeling guilty and induce self-doubt, even if they weren’t at fault to begin with. They may offer apologies, uncertain what they did wrong, yet continue to try to resolve the situation.

When you name the pattern for what it is, by acknowledging the manipulative aspect of harmful silent treatment, you finally take a step toward regaining your agency.

2. Set Strong Boundaries And Seek Support

The silent treatment is also often used to guilt-trip you when you try to set necessary boundaries. You tell your partner you’re going out with friends over the weekend, and the next day, you get no response from them. You ask, “Hey, what’s wrong?” only to be met with silence.

You have an inkling it’s about your friends, so you bring it up, and suddenly they express how hurt they feel that you’d rather spend time with others than with them. Before you know it, you find yourself apologizing for upsetting them.

You try to tell them you need space, only to be shunned again for expressing your needs. Every time you try and set a boundary, one way or the other, you end up on the receiving end of silent treatment over the perceived slight.

To them, you setting boundaries is a sign of rejection, and they cut off all your access to them, leaving you begging for scraps of attention. In the end, you will always find yourself apologizing for having needs and communicating them.

Research published in Basic and Applied Social Psychology explored the impact of silent treatment on both the individuals who used it and those on the receiving end.

For those on the receiving end, here’s what they found:

• Ambiguity enhances harm. Targets who were unable to clarify why they were being neglected felt greater threats to belonging, self-esteem and meaningfulness. This ambiguity made their hurt worse.

• The feeling of invisibility exacerbates results. When targets sensed the ostracizer behaved as if they didn’t exist, the threats to their welfare were even greater.

• Compensatory behavior is the go-to. These individuals were more likely to pursue new social ties in order to regain a feeling of belonging.

For partners using the silent treatment, these were the effects:

• People with high self-esteem were more likely to use ostracism as a relationship-ending strategy and were also more likely to walk away from partners who used it against them.

• Those with low self-esteem were more likely to use silence as a defensive response to criticism or rejection and were more likely to report feeling ostracized more frequently themselves.

Even though those who used silent treatment often viewed it as an effective conflict resolution tool, the ones on the receiving end saw it very differently. For them, it led to hurt, withdrawal and resentment rather than any meaningful resolution.

Silent treatment undermines your self-esteem, and it’s necessary to set firm boundaries and be willing to walk away if those boundaries are not respected.

When you see your partner using the silent treatment to get their way, you can say, “When you cut off all communication, I feel hurt and alone. I really care about our relationship. If you want to take your time, I understand, but it would be helpful if you could give me an idea of how long you need and when I can talk to you again.”

Seek the support of your friends and family; this tactic often leads to isolation, where you may end up internalizing the blame. Instead of solving problems together, you feel like you are the problem. Seeking the support of your friends and trusted individuals can help you see it from a different perspective and regain your sense of control.

Destructive silent treatment creates an imbalanced power dynamic in the relationship. Healthy love can withstand conflict, boundaries and differences, but it cannot thrive in silence that punishes rather than heals. If your partner chooses to communicate through absence, you have the right to choose presence for yourself.
