Everyone has quirks and traits that you may not like, but when you accept someone, you accept the “bad” along with the good. Dr. Ramani Durvasula, licensed clinical psychologist, professor of psychology, and author of Should I Stay or Should I Go: Surviving a Narcissistic Relationship, explains. “Acceptance doesn’t carry that ‘I wish it was different’ theme,” she tells Bustle. “Acceptance really has, at its core, the idea that this is who the person is — and you are fine with it. Meanwhile, ‘tolerating’ doesn’t have the same ‘I am fine with it’ mentality.”

In a relationship, each person has certain wants and needs, and hopefully they match up more so than not. That said, some wants and needs will differ, and that’s when your attitude comes into play. “The difference between accepting and tolerating your partner relates to the emotion and thoughts underneath your behavior,” Dr. Elizabeth Cohen, clinical psychologist, tells Bustle. “Both tolerating and accepting behavior looks the same from the outside.” For example, if your partner has a weekly hang-out plan with their best friend, you can say, “Great, have fun,” which can be interpreted as either accepting or tolerating, she says.

Dr. Cohen adds that, while your partner’s out, you may think: “When are they coming back? I wish they would hurry up. Why do they even do this?” Or, you may think: “I am glad they have the chance to go out and spend time with their friend. I’m grateful my partner is so open with me about their needs and that I don’t have to be the only person who can give them attention and have fun.” See the difference?

No one likes to be judged, and if you’re judging your partner, you’re not wholeheartedly accepting them. “Acceptance tends to be a more holistic and perhaps even a loving state,” Dr. Durvasula says. “You recognize that this is who the person is, and you do not judge them.”

Meanwhile, if you only “tolerate” them, this implies that you’re chronically uncomfortable with their behavior(s), she says. “It’s a bit of a white-knuckle teeth-gritting experience and doesn’t tend to work well in the long-game, because it is exhausting and uncomfortable,” Dr. Durvasula says. “Their behaviors or attributes may get under your skin and may feel unpleasant, and there is an ongoing undercurrent of wishing they were different.”

Do you accept your partner or do you try to change them? “If someone has a true dealbreaker for you, and you stay in the relationship anyway, you’ll always be tolerating that behavior, which will lead to resentment and contempt,” Sandy Weiner, chief love officer of Last First Date, tells Bustle.

She says that a clear example of this is having religious differences. “Say you’re a devout Christian and your partner is an atheist,” Weiner says. “You really wanted to be with someone who goes to church with you and shares your beliefs, but they refuse.” She says your partner has many other wonderful traits, but this religion issue keeps coming up.

“If you can’t respect — and accept — each other’s beliefs, it will probably not work out,” Weiner says. She adds that respecting each other’s differences is key when it comes to accepting them. “If you can *accept* each other’s differences and not try to change the person, there’s a good chance you can have a harmonious relationship.”

If you and your partner accept each other, you probably don’t find qualities in them that repeatedly annoy you. “The difference between accepting your partner for the way they are and tolerating them is fairly huge,” psychologist Shae Vian tells Bustle. “When you accept your partner for the way they are, you won’t find yourself irritated or annoyed anymore by their behavior, as you accept that you can’t change this.”

For example, Vian says that she once had a husband client complain that it annoyed him how much his wife would often leave the car door unlocked in the driveway; he tolerated it, but it still would still wind him up. “Through working with him, he came to accept that she didn’t do this on purpose and was likely juggling so many things with the kids, she would forget,” Vian says. When you’re tolerating someone, Vian says, you’re consciously trying not to let the behavior irritate you — but when you accept it, it requires much less effort.

Once upon a time, perhaps things your partner did annoyed you, but now you’ve come to accept those things and see the plus sides of them, so they’re no longer an issue. “Acceptance is when you take everything, good and bad,” Paul DePompo, PSyD, ABPP, board certified CBT therapist at the Cognitive Behavioral Therapy Institute of Southern California, tells Bustle. “You are not irritated in an unhealthy way by the aspects in your partner that you wish were different.”

Instead, he says, you are able see that every annoying trait has its flip side as a good thing — if they’re arrogant, you probably like their intelligence, or if they’re selfish, you probably admire their ability to self-care. “When you are just ‘tolerating,’ you feel your patience bag is slowly reaching the top, and you’re hoping nothing more gets added,” Dr. DePompo says.

If you’re in a codependent relationship, it may be easy to lean toward tolerating your partner’s behaviors more so than accepting them. “When partners tolerate each other’s behavior instead of fully accepting it, they are at risk of codependency,” Christina Vazquez, psychotherapist and author of The Uncherished Wife: Recover from the Emotionally Absent Man, tells Bustle. “Codependency can wear many faces, but by not speaking to your partner transparently about your preferences, wants, or values, you’re being emotionally dishonest with yourself and with them, resulting in resentment.”

She says that acceptance feels more neutral or indifferent — and has the potential to move towards appreciation or fondness — while tolerance feels like the emotions of annoyance, irritation, and tension, which can show up in behaviors of criticism, sarcasm, and judgment.

“For example, let’s say your partner is a die-hard football fan, spending most of [their] Sundays in front of the TV,” Vazquez says. “You hate football, but don’t have the heart to tell [them] because it would mean less time together on the weekends. Instead, you sit there, frustrated for hours, thinking of all the other things you could be doing together that would be mutually enjoyable.” Since you’re annoyed, this example is more on the being-tolerant side versus the being-accepting one, she says.

When you accept your partner, there are more “good” days than “bad” days, and for good reason — no pun intended. “When you are accepting, you can still carry on with your partner and have enjoyment, despite their imperfectness,” Dr. DePompo says. “Conversely, you are ‘tolerating’ them when you often think negative thoughts about them or argue back about things that are not likely to change.”

Similarly, Dr. DePompo also says to pay attention to your daily patterns with your partner to determine if you are more accepting or tolerating of them. “If an average day has good patterns between the two of you, you are likely quite accepting,” he says. “But if there are arguments, you are talking about them to your friends, and/or are preoccupied with negative interactions during the day or at bedtime, you are likely tolerating them.”

When you’re in the thick of a relationship, red flags and intolerance may dominate it more than not, yet you still stay together. Usually, this is because you are *tolerating* your partner, not *accepting* them. “The biggest difference I see in tolerance and acceptance in a romantic relationship has to do with justification for staying together,” Julio Briones, personal crisis manager and CEO of AnswerMan Specialty Services, LLC, tells Bustle. “As a personal crisis manager, one of the functions I serve is helping individuals and families understand the issue of tolerance versus acceptance, so they can work through the situation and stay together, whether one is going to rehab, prison, you name it,” he says.

Briones says he often asks people: “Do you want to try to make this work?” He says this is an important question, because if the couple wants to make it through the trials ahead, they have to accept the situation and their partner, with all their faults. “If a person just tolerates who their partner is, using different justifiers such as, ‘I HAVE to because of the children’ or ‘I HAVE to because it is what is expected after all these years,’ this mentality will usually lead to resentment and, in some cases, bitterness.”

There you have it — the difference between if you’re accepting or tolerating your partner, according to relationship experts. Like Dr. Cohen says above, the key difference is how you feel and think in a given situation.

Nancy Cramer, leadership consultant and founder of Correct Course Counseling, has a guiding philosophy she uses with her clients. “If things do not add up, something is missing,” she tells Bustle. She says one client was constantly getting sideswiped by anger from his partner for no apparent reason; no matter what changes he made to his behavior, he was always facing an angry response. “If you consistently leave conversations and confrontations wondering ‘What just happened?’ then you are in a situation where your partner may be tolerating you instead of accepting you,” Cramer says. “Accepting someone includes appreciating them for who they are and loving them for their differences whereas tolerating someone focuses on their irritating qualities.”

As you can see, the above experts make it easy to tell the difference between whether you’re accepting your partner or tolerating them. Once you determine which one is dominating your relationship, you’ll have to decide how to proceed (or not).
