You might be worried about the flu and other physical ailments that start circulating this time of year. But a contagion of a very different kind was the subject of a recent story in the Chicago Tribune.

The Tribune took a look at how divorce can spread through social circles. It cites a study that found you’re 75 percent more likely to get a divorce yourself if a friend has divorced. Even a friend of a friend getting a divorce raises your own chance of divorcing by 33 percent.

Why does this happen? In the article, relationship expert Helen Fisher says friends’ divorces prompt us to reassess the condition of our own marriages.

Just as physically ill people are hit harder by sicknesses like the flu, your marriage can also suffer from a weakened “immune system.” When your marriage is compromised, you may find yourself fantasizing about leaving, especially if a close friend has already taken that step.

Here are a few tips so you won’t unintentionally fall victim to the divorce contagion. It’s all about strengthening the health of the emotional connection between you and your spouse.

Take Care of Yourself

It’s hard to emotionally connect with anyone when you are running yourself ragged. Sleeping enough, eating well and managing stress make it more likely you will have the bandwidth to connect with your partner. Don’t forget to also make space for the people and activities you deeply enjoy. If you’ve been neglecting hobbies and interests, take some time to renew your passions. Have you lost touch with a dear friend? Reach out today. This can keep you from feeling that you’ve “lost yourself” — and that you need to leave your marriage to find yourself again.

Get Deliberate About Being Positive

Research shows that marriages stay strong when spouses share far more positive interactions than negative ones. But when we’re busy and stressed (which, for most of us, is always!), it’s easier to notice all the negatives. This week, try to intentionally look for and tell your husband how much you appreciate his good qualities. Be affectionate, playful, and compassionate to increase the positive even more. Keeping your  “emotional bank account” full with positives prevents it from being overdrawn in difficult times.

Seize Every Moment

Juggling the responsibilities of adulthood can make it hard for you and your husband to even “se” each other. When we focus exclusively on what we need to get done, and not on our partners, that intimate connection frays, little by little. You don’t need a two-week romantic vacation to rekindle your intimacy. (Although I’m very much in favor of taking one if you can!) Instead, take advantage of the small moments in your day — like when you both come home after work — to connect.  Investing even a little bit of time each day strengthens your relationship. Check out the Gottman Institute blog for a great resource on this topic:  “6 Hours a Week to a Better Relationship.”

The reality of contagious divorce is alarming, but it also serves as a powerful reminder to take care of your relationship. If you’d like a total “wellness guide” for your marriage, I invite you to check out my book Strong Women, Strong Love.
