One of the most common and most damaging mistakes couples make in marriage is assuming.
Assuming your spouse knows what you need.
Assuming they understand how you feel.
Assuming love means they should “just get it.”
Assumptions feel harmless, even logical. But over time, they quietly erode connection, intimacy, and trust.
Assumptions Are the Enemy of Intimacy
Assumptions replace communication with expectations. And unmet expectations almost always turn into disappointment.
When we assume, we stop asking questions.
When we stop asking questions, we stop learning our spouse.
And when learning stops, intimacy fades.
Marriage is not sustained by mind-reading, it’s sustained by ongoing dialogue.
“I Thought You Knew” Is One of the Most Dangerous Phrases in Marriage
Many marital conflicts don’t begin with betrayal or major conflict. They begin with silence.
- “I thought you knew I needed help.”
- “I assumed you weren’t interested anymore.”
- “I figured you’d tell me if something was wrong.”
But according to Drs. John and Julie Gottman, successful marriages are built on turning toward each other, not assuming the other person will speak up every time.
The Gottmans’ research shows that couples who consistently acknowledge and respond to each other’s “bids for connection” are far more likely to stay together. Ignoring those bids—often because of assumptions—creates emotional distance over time.
Assumptions Create Emotional Gaps
When communication stops, gaps form. And gaps rarely stay empty.
According to the American Psychological Association, lack of emotional connection is cited in nearly 67% of divorces—more than finances, conflict, or infidelity.
That emotional disconnect often begins with unspoken assumptions:
- “They know I’m overwhelmed.”
- “They know I don’t feel desired.”
- “They know I need more affection.”
But knowing requires hearing, and hearing requires communication.
Assumptions Kill Sexual Intimacy Too
Sexual intimacy suffers greatly under assumptions.
- Assuming rejection instead of asking
- Assuming disinterest instead of discussing desire
- Assuming sex “just happens” instead of intentionally prioritizing it
Dr. Pepper Schwartz, a sociologist and relationship expert, notes that couples who talk openly about sex report higher satisfaction and stronger emotional bonds than couples who avoid the topic.
Silence around sex often communicates:
“This part of our relationship doesn’t matter anymore.”
And when intimacy goes unspoken, desire often goes unshared.
Why Communication Is the Lifeline of Marriage
Healthy marriages are not conflict-free; they are communication-rich.
Communication:
- Clarifies expectations
- Prevents resentment
- Builds emotional safety
- Strengthens trust
- Keeps intimacy alive
The Gottmans estimate that 69% of marital conflict is perpetual meaning it will never fully go away. The difference between thriving and struggling couples isn’t avoiding issues, but how they talk about them.
Communication Is a Skill, Not a Personality Trait
Many couples assume:
- “We’re just not good communicators”
- “That’s just how I am”
- “Talking won’t change anything”
But communication is learned. It improves with:
- Practice
- Humility
- Willingness to listen
- Curiosity instead of defensiveness
Marriage isn’t about being understood automatically, it’s about choosing to understand intentionally.
How to Stop Assuming and Start Communicating
- Ask Instead of Guessing
Replace assumptions with curiosity. Ask questions even when you think you know the answer. - Say What You Feel, Not What You Expect
“I feel disconnected” opens doors.
“You never listen” closes them. - Check In Regularly
Don’t wait for problems to surface. Build habits of honest conversation. - Talk About the Hard Stuff Early
Silence doesn’t protect peace—it postpones conflict. - Create Emotional Safety
When your spouse feels safe to speak, they will.
A Final Thought
Marriage doesn’t fall apart because couples talk too much.
It falls apart because they stop talking at all.
Assumptions feel easier than conversations, but they cost far more in the long run.
Healthy marriages are built on this simple but powerful truth:
Love doesn’t assume. Love asks. Love listens. Love responds.
