Flexible vs. Non-Negotiable Boundaries in a Relationship

A boundary is a limit you set on what you will and won't do, and holding your boundary well means knowing when to stay firm and when to bend. If you let your boundaries go every time to keep the peace, you may hold your frustration in until it comes out over something small, like who gets the bathroom first. On the other hand, if you refuse to bend on any limit, you may end up in arguments with your partner over things that don't matter much to you. 

There are three levels of boundaries that you can hold in a relationship, which are preferences, important needs, and hard no's, and understanding these boundaries can help you learn when to stand your ground and when to let go. The sections below walk you through each level and show you how to sort your own needs.

The three levels of boundaries at a glance

The table below shows how the three levels of boundaries compare, and the sections after it explain each level in more detail.

Preferences are things you can let bend

A preference is something you enjoy and would rather keep, but you can let it go without much hesitation. Say you love having the first cup of coffee in the morning before anyone else is up. It feels good, and you'd like to keep it. If your partner beats you to the coffee maker one day, you may feel a small pinch of annoyance, but you probably wouldn't call that a boundary being crossed.

A preference doesn't cost you much to let go, so you can let your partner have their way without feeling like you've lost something. You don't have to defend every small thing you like, and knowing that can take a lot of pressure off.

Important needs are boundaries you can bend when needed

An important need matters more to you than your preference, and you protect it by setting a boundary around it. Sleep is a good example. You might aim to be in bed by 11 and up by 7, and you might decide that you won't take calls, scroll your phone or read email after 10. You set that boundary for yourself because you know how you feel and function without enough rest.

A boundary like this can still be flexible when you need it to be. A friend's late flight, a sick child or a work deadline might push your bedtime back, and making an exception in that situation is okay. When you know a need is important and flexible, you can bend it on purpose and go back to your routine the next night, instead of feeling like you failed at keeping it.

Hard no's are boundaries you hold every time

A hard no is a boundary you hold every time, because crossing it goes against your values and how you want to show up with the people you love. Being yelled at by your partner is one example, and what counts as a hard no depends on your own values. You may find it helps to think of your boundaries as a fenced yard, where you decide who comes in and what grows there. If someone starts digging up your roses, you ask them to stop right away. When someone crosses a hard no, you respond just as quickly.

Say your partner starts yelling in the middle of a disagreement. If being yelled at is a hard no for you, you can say, "I'm not willing to stand here and be yelled at. I'm leaving the room," and then leave. Say it more than once if you need to, since a person who is yelling may not hear you the first time. When you say it clearly, you give your partner three things to hear, which are what is happening, what your boundary is and what happens if it's crossed.

You control whether you leave the room. You decide what you're willing to stay present for, and because the boundary is about your own actions, you don't have to wait for your partner to change for it to work. 

How to sort your own needs into the three boundary levels

The good news is that you can sort your needs easily. Write three short lists, one for each boundary level, and begin with the needs that come to mind first.

• Under preferences, list a few things you enjoy and would be okay letting go of.
• Under important needs, list a few things that matter to you and note when you would make an exception.
• Under hard no's, list the few things that go against your values, since a short list is easier to adhere to.

Then pick one hard no and say the exact words out loud once, so they feel familiar to you. When things are calm and you're not in the middle of an argument, you can share your lists with your partner. If your partner hears your hard no ahead of time, they can understand why it matters to you.

Common questions about flexible and non-negotiable boundaries

Q: How do I know which boundary level a need belongs to?

A: You can ask yourself how much it would cost you to let go of this need. If you'd barely notice, it may be a preference. If this need matters to you but you could make an exception, it may be an important need. If giving it up would go against your values, it may be a hard no.

Q: What if my partner puts the same need at a different level?

A: You can talk about it. Share why the need matters to you and ask how your partner sees it. You may find that something that's a preference for one of you can be an important need for the other.

Q: What if someone crosses my hard no?

A: You hold the boundary every time, saying the same thing and taking the same action, like leaving the room. If your partner keeps crossing your hard no, or the strain is affecting your work, your sleep or your health, a therapist may help.
