If you want your marriage to last, it’s important to pay attention to the habits you’ve developed in your relationship. It’s not always major issues like infidelity that lead to divorce; sometimes, small everyday habits can contribute to a relationship’s demise. “It’s easy for small habits to start leading a relationship off track,” says Allison Zamani, an associate marriage and family therapist. “A relationship requires both parties to feel connected to one another. Connection is powerful if you can maintain it, but it also requires effort.” Zamani notes that many couples seek therapy not because of one specific conflict but because they no longer feel connected. “This starts with something small,” she explains. For instance, one partner might be stressed about work and choose to deal with it alone, leaving the other partner feeling confused and disconnected. The key is to develop habits that increase connection and eliminate those that create distance. Here are seven surprising habits that can lead to divorce, according to studies.

1. Being Overly Affectionate During the Newlywed Phase

A study published in the Journal of Personality and Social Psychology found that couples who were overly affectionate in the early years of marriage were more likely to divorce after seven years. The intense passion at the beginning isn’t always sustainable. Once the honeymoon phase ends and reality sets in, some people realize they aren’t as compatible as they thought. This can lead to a decrease in affection and an increase in ambivalence. However, this doesn’t apply to all affectionate couples. This research mainly pertains to couples who married based on intense chemistry without a solid foundation for a healthy relationship.

2. Avoiding Confrontation

A 2018 study by the American Psychological Association found that withdrawing or shutting down during confrontations can negatively affect your relationship. While some people avoid confrontation to keep the peace, this habit can make their partner feel ignored. A “demand-withdrawal” dynamic can be particularly harmful to higher-income couples who have access to resources to resolve marital problems. When one partner isn’t interested in working things out despite having the means, it creates tension.

3. Letting Debt Pile Up

Money issues can strain any relationship, especially if partners aren’t on the same page. Research by the Federal Reserve Board shows that couples with significant differences in credit scores are more likely to separate within five years. People with higher credit scores tend to have longer-lasting relationships. Additionally, a survey by Student Loan Hero found that one in eight couples blamed student loans for ruining their relationship.

4. Arguing Over Chores

A 2018 study from Harvard Business School found that 25 percent of couples listed “disagreements about housework” as a reason for divorce. Couples who could outsource basic household tasks were generally happier. After a long day at work, the last thing you want to do is wash dishes. If your partner isn’t doing their fair share, it can lead to arguments and greater dissatisfaction with your relationship.

5. Playing “Fortnite”

A study by Divorce Online found that in 2018, at least 200 divorce petitions cited the video game “Fortnite: Battle Royale” as a reason for divorce. The addiction to the game can cause problems within the relationship. A 2014 Pew Research report found that one in five people said technology use negatively affected their relationship, and a quarter said their partners were distracted by their smartphones during couples time.

6. Venting About Your Relationship

A study published in the Journal of Family Psychology by John Gottman and colleagues found that how you talk about your relationship can predict divorce. Participants who spoke negatively about their relationship or showed signs of disappointment were more likely to separate.

7. Being Jealous of Your Partner’s Success

A 2018 study by Swedish researchers found that women who earned less than their husbands at the start of their marriage were twice as likely to get divorced once they became more successful at work. Women who moved into leadership roles were less likely to stay married than those who didn’t achieve higher positions. Researchers believe this is because successful women are more likely to leave inflexible relationships with less support. Socialized gender roles may also play a factor. These findings applied to marriages where wives started off earning less than their husbands. Keep in mind that issues like fighting over chores or video game addiction don’t directly cause divorce. However, they can contribute to distance in the relationship. When there’s distance and negativity, you’ll need to work together to overcome it if you want your relationship to last.
