“Boundaries” isn’t the most romantic word, is it?

Or at least it’s not the first word that comes to mind when you think about the qualities of a successful marriage. Talking about boundaries doesn’t get us as starry-eyed as talking about love, passion and devotion.

But boundaries are essential. A recent article called “What Are Healthy Boundaries To Set In Relationships? 15 People Reveal Their Wisest Guidelines” got me thinking about the different kinds of boundaries we can set in our marriages and why they’re so beneficial.

Boundaries around Your Individuality

Is your whole life about your marriage and family? Is your husband your only source of emotional support? Do you neglect your health, your basic needs or the hobbies and interests you had before you got married? Then you need some healthier boundaries around your sense of self.

Maintaining a strong sense of yourself isn’t selfish. Neither is tending to your own needs on a regular basis. The reality is that nurturing your independence makes you a better partner. You take pressure off your husband because you’re not looking to him to fulfill all of your needs.

Having a life outside your marriage can also bring fresh energy into your marriage by giving you other experiences to share with your spouse besides the household chores. Your separateness also sends a strong message about how much you value yourself – and that can make you much more attractive to your husband. You may even lower the chances one of you will have an affair. Psychotherapist and bestselling author Esther Perel believes that many people stray from their marriages because they are trying to recapture a part of themselves they lost by getting married.

Boundaries around Privacy

True love doesn’t necessarily equal being a completely open book. You and your husband can have very different boundaries around privacy.

For example, let’s say both you and your husband were married before. You feel comfortable talking freely about your ex with your husband. No detail is off limits. On the other hand, your husband is more reticent in talking about his previous marriage. He does share information that’s relevant to your relationship – like how his ex’s overspending affects his behaviors around money in your relationship. But overall he keeps most things about his first marriage private.

Your approach may baffle him, and vice-versa. But neither of you is necessarily wrong. The important thing is that you can each maintain the privacy boundaries that feel healthy to you and that you understand and respect each other’s boundaries.

Boundaries around Behavior

Every marriage has rules about off-limits behaviors, whether those rules are spoken or not. Almost all of us would agree that having sex with other people and physically or emotionally abusing your spouse are clear boundary violations in a marriage.

But beyond these common rules, there are some other, lesser-known boundaries that are critical to a healthy marriage. Specifically, fighting dirty and openly disrespectful behavior should be unacceptable in your marriage. Displaying contempt  is one of the top warning signs that your relationship is headed for divorce. Tolerating disrespect in any form will ultimately damage your relationship, so it is vital you put some clear boundaries around it.

Other behavior boundaries in marriage are important to negotiate. For example, different couples might set different boundaries around social media use. You may need to discuss how you feel about each of you having friends of the opposite sex. You may even have boundaries you want to set around how often you have sex or how household responsibilities are shared.

It’s essential to talk about what the boundaries are in your marriage and to make sure that you’re both playing from the same rule book.

This week, take some time to think about the boundaries in your marriage. Are there any boundaries you want to change? Are there boundaries that you and your husband need to communicate more about?
