19 Signs Of A Toxic Relationship & What To Do If You're In One

Ever had someone in your life who dragged you down or made you doubt yourself? It's very possible you were dealing with a toxic relationship. We've all heard the term, but what does it really mean? And more importantly, what can be done about it? 

Certain themes, like codependency and narcissism, are also common in toxic relationships. As therapist Wendy Behary, LCS, tells mbg, "Any toxic relationship implies there is something potentially damaging for the person (or both people) in that relationship." These relationships can leave you doubting your own reality, your own values, and your sense of self-worth. 

Toxic relationships can result in a lot of self-abandonment, Behary explains. "You feel you have to forfeit your voice, your opinion, your wishes and wants, and your own needs."

"Toxic relationships are also relationships where you don't feel accepted for who you are; you may feel like an outsider, shunned, or judged constantly," functional medicine practitioner Will Cole, D.C., IFMCP, tells mbg. With enough self-abandonment, you'll begin to feel like you're losing yourself. You may feel erased, invisible, or unfamiliar to yourself. You may find yourself doing things you never thought you would, doubting yourself and your values. 

"Toxic relationships are very lonely," Behary says. "These relationships create a great sense of loneliness because the true sense of intimacy is not there—it's devoid of real personal connection and empathic attunement." (Here's more on why you might feel lonely in a relationship.)

Healthy relationships bring out the best in both partners. Toxic ones will do the opposite. "Some people are just horrible matches for each other," Melamed notes. "Some people just bring out something in the other person that is just horrific."

"A toxic relationship is a relationship that consistently leaves you feeling drained, bad about yourself, or emotionally or physically unsafe," Cole explains. "Consistent means this is how you feel more often than not after hanging out with this person. This is key."

"Usually toxic relationships involve an unequal amount of give and take, where one person must give a lot and receives very little in return," Cole says.

In toxic relationships, particularly if a narcissist is involved, Behary says there will be a certain level of control where one partner may dominate the other. This can be more literal but also emotional, she says, such as "making them feel as if they're not good enough or their partner is the only one who has any say in what's going on."

Where there is controlling, there is often jealousy. Toxic relationships often stem from insecurity or a need to control certain situations. Jealousy can manifest from these behaviors and patterns.

If your partner is constantly isolating you, perhaps even turning you against your friends and family, that's a major red flag. In a toxic relationship, partners may manipulate each other into "needing" each other—and isolating each other away from other relationships. This enmeshment can sometimes feel like closeness and bonding, when in reality it stems from unhealthy codependence. 

Oftentimes in toxic relationships, especially codependent ones, Melamed says, one partner may have a substance abuse or unchecked mental health issue they're not getting help with. When this happens, the other partner may tiptoe around it or even enable it. "One person may like the fact that the other has an unchecked issue because it allows them to stay in control of the other person," she adds.

"Usually, in toxic relationships," Behary notes, "you're consistently undermining or causing harm to your partner." This can play out in a number of ways, but the general idea is that there isn't a sense of camaraderie but rather disdain and resentment.

Along with isolating each other and controlling each other, other forms of emotional and psychological abuse are also likely present in a toxic relationship. This can look like explosive arguments, one or both of you belittling the other, rejecting each other's realities, lying, manipulation, and so on.

This one goes without saying, but any physical violence—including pushing, shoving, grabbing someone's arm so hard it hurts, and any other physically aggressive act—is a clear indication that there is a pathology within the relationship that's causing direct harm to one or both of you.

One of the more common forms of psychological abuse that directly links with narcissism and toxic relationships is gaslighting. Gaslighting happens when one partner denies the reality of another, manipulating them into doubting the validity of their own emotions and needs. (Here are signs of gaslighting in relationships.) 

Partners in a toxic relationship will find it nearly impossible to work through disagreements. "I always say in healthy relationships, when you're fighting, you're not fighting each other, you're fighting for the relationship to work out," Melamed notes. "And that's where things like healthy compromise come in—trying to take the other person's perspective with empathy and vulnerability."

Because communication is so difficult, it can leave one or both partners feeling unheard, which will brew resentment. "One person or both people resent the other person," Melamed adds, "and think the other person owes them something. And that's usually their own sense of self-worth."

If you're in a toxic relationship that's been going on for a while, you may have noticed a pattern emerge; things never go smoothly for long, and you aren't surprised when the toxicity rears its head. Yet for some reason, you can't walk away (yet).

If one person is calling all the shots, Melamed and Behary both note that's not a good sign. Both partners should be on board with big decisions, and if one is always pushing for more, that's an indication of an imbalance. Research shows power imbalances between couples can cause significant strain on the relationship.

Lastly, trust your community. If the people who've known you before this partner rolled around have real concerns about your relationship, that's not something to ignore. Especially in toxic relationships, it's important to get the take of someone who's not wearing rose-colored glasses.

These issues include but aren't limited to:

"When you're bracing yourself for criticism, judgment, for having to really be on your toes because you're walking on eggshells," Melamed notes, "you're in a constant state of low-grade anxiety and constantly in fight-or-flight. Depression is at play too."

Due to the way toxic relationships can lower self-esteem, plus the stress they cause, this can result in appetite changes and weight loss, Melamed says.

Stress causes inflammation1—that's no secret. And inflammation is an underlying cause of a host of issues, from digestive problems to skin breakouts and more.

Stress and inflammation also both lower your immunity, Melamed says. Research has shown that high levels of stress can actually stir dormant infections, such as herpes2.

As we're all aware, nothing ruins a good night's sleep like stress, and toxic relationships can definitely keep you up at night. "Sleep deprivation can even be used to control other people," Melamed adds. 

Yes, it really goes that far. "When you're feeling threatened," Melamed notes, "your nervous system releases stress hormones like adrenaline and cortisol. When that's chronic, it can wear you down and become hard to shut off, creating so many issues like increased risk of heart attack and stroke3."

For this reason, it's important to reflect on what we saw growing up. "If we grew up in a household where we saw unhealthy relationships, or around our friend group, or in our community we saw unhealthy relationships as models, it's easier to think that it's normal, acceptable, or just the way things are," Melamed says. "It can also come from having lower self-esteem or a lower sense of self-worth and not understanding what a healthy relationship looks like."

Here's a step-by-step guide on how to fix a toxic relationship. 

If you're married, Behary says it's important to be prepared with all the files and information you might need, plus a savvy lawyer, to help you proceed. Additionally, she says the most important thing is to make time to care for yourself and lean on your support systems as necessary throughout this process.

Toxic relationships are incredibly challenging to deal with, but once you realize what needs to change, you can potentially overcome your issues—or walk away. Either way, there are always lessons to be gained. As Behary says, "Once we realize our health and welfare really matters, it's a journey worth taking."
