Common Marriage Mistakes: 10 Relationship Habits That Do Real Damage
Last updated October 29, 2026 by the Marriage Bliss Editorial Team.
The most common marriage mistakes are small habits couples start treating as normal: keeping score, avoiding hard talks, putting the kids or work first every time, and speaking with contempt. None of them feels like a crisis on its own, which is exactly why they last. Below are 10 bad relationship habits couples tend to excuse, why each one does damage over time, and what to do instead.
At a glance
- The most damaging habits are quiet ones: avoidance, contempt, and neglect.
- Most are easy to fix once you name them.
- Replace each habit with a specific alternative, not just “try harder.”
- If a pattern involves fear, control, or addiction, it needs more than a habit change.
1. Keeping score
“I did the dishes three times this week; you did them once.” Tallying turns the marriage into a ledger. Instead: agree on a fair split of the big things, then give generously on the small ones. See dividing chores in marriage.
2. Avoiding hard conversations
Swallowing every complaint feels peaceful until resentment builds. Instead: raise one issue at a time, calmly and early. Our rules for fighting fair make it safer.
3. Treating contempt as humor
Eye-rolling, mocking, and sarcastic digs wear down respect. Researchers rank contempt among the strongest predictors of divorce. Instead: state the complaint directly without the insult. See the four horsemen.
4. Putting everyone else first, always
Kids, work, and extended family all deserve time, but a marriage that gets only leftovers starves. Instead: protect a weekly date and a daily check-in. See marriage after baby.
5. Going quiet instead of talking
The silent treatment punishes rather than resolves. Instead: say “I need a break and will come back in an hour,” then do. See the silent treatment.
6. Secrets about money
Hidden spending or debt erodes trust fast. Instead: hold a regular money meeting with full transparency. See managing money in marriage.
7. Taking your spouse for granted
Years in, thank-yous fade. Instead: thank them for something specific every day. See tiny ways to make your spouse feel loved.
8. Venting about your spouse to everyone but your spouse
A little venting to a friend is normal; making it the main outlet creates a gap between you. Instead: bring the complaint to your spouse first.
9. Letting intimacy fade without a conversation
Many couples drift into months of no affection and never discuss it. Instead: talk about it kindly and make a plan. See building intimacy in marriage.
10. Assuming it will fix itself
Problems rarely vanish on their own. Instead: address them early, with a counselor if needed. See our guide to finding a counselor.
When it’s more than a habit
If your spouse controls, frightens, or demeans you, that’s different from a bad habit. See signs of manipulation in marriage, or contact the National Domestic Violence Hotline at 1-800-799-7233 (text START to 88788).
Bad habits and better replacements

How to change a habit together

- Check in after two weeks.
Her side, his side
Her side: “I didn’t realize how often I vented about him to my sister until he overheard it.”
His side: “I go quiet when I’m upset and call it ‘keeping the peace.’ She experiences it as being shut out.”
Most bad habits start as ways to protect ourselves. Naming them is the first step to changing them.
