Every couple walks down the aisle accompanied, symbolically, by the families who raised them. These early family systems, whether healthy or dysfunctional, shape our emotional patterns, communication styles, and expectations of loyalty. After the honeymoon fades, many newlyweds realize just how much those systems still exert influence, especially through the involvement of in-laws.

The challenge isn’t that extended family is involved. It’s that, without conscious boundary-setting, their involvement can sometimes create pressure, divide loyalty, or even drive a wedge between partners. Be sure to take our Florida premarital course here.

Understanding Triangulation

In psychology, triangulation happens when a third party, often a parent, is drawn into a conflict between two people, typically to diffuse tension or gain validation. In marriage, this might look like a spouse complaining to their parent instead of discussing the issue directly, or a parent undermining their child’s partner under the guise of “helping.”

Triangulation creates emotional confusion, erodes trust, and subtly prioritizes old loyalties over the new family unit. While it may feel easier in the moment, it tends to increase long-term resentment and marital instability.

A United Front Is Not a Fortress

Some couples fear setting boundaries will cause friction with family. But it’s not about creating enemies, it’s about creating clarity. When both partners present a shared message to their respective families, it signals maturity, unity, and mutual respect.

A united front doesn’t mean blind agreement on everything. It means that external voices don’t get to divide the team. Conflict should be managed within the couple first, with families included only when there is consensus and consent.

Evidence-Based Tips for Setting Boundaries With Strength and Empathy

1. Decide Privately, Present Publicly:
Talk about in-law boundaries as a couple, without outside input. Once you’ve agreed, present your decisions (e.g., holiday plans, childrearing preferences, living arrangements) together, calmly and confidently.

2. Use “We” Language:
“We’ve decided…” communicates unity. It leaves less room for manipulation or triangulation and gently reinforces that your marriage is its own entity.

3. Acknowledge Family Emotions, But Stay Firm:
It’s okay to validate a parent’s feelings (“I know it’s hard not seeing us every weekend”) while still holding the line (“We also need time to settle into our own routines.”).

4. Reassure, Don’t Retreat:
Boundaries aren’t rejection. Assure family members that love and connection remain, even as roles and access shift. This helps reduce defensiveness and keeps relationships intact.

5. Seek Support if Needed:
If family dynamics feel too complicated or heated, consider couples therapy or a structured premarital course like the Florida Premarital Preparation Course to strengthen your communication and boundary-setting skills.

Your Marriage, Your Circle

Healthy boundaries with in-laws are not a sign of conflict, they’re a sign of care. When a couple defines their shared space and communicates with respect and unity, they create a circle of safety that allows both partners to thrive, together and as individuals. Protect that space early, and you protect your peace for years to come.
