“We’re getting a divorce,” she explained, with a look of disappointment on her face.

Her tone of voice changed, as she tried to look on the bright side. “But it’s for the best. Things haven’t been working out for the past few years. We’re just too different.”

“For the best…Too different….” Her words echoed in my mind for hours after our conversation ended. I thought about the list of differences my husband and I possess. We are SO different in so many ways. Could it really be possible that a couple can be “too different” to have a thriving marriage? The thought didn’t sit well with me.

As a Professional Counselor, every day I see couples who come into therapy with their marriage on life-support. But their struggles often have nothing to do with the trauma of affairs, addictions, or abuse. Instead, they are dying a rather slow and painful death.

Phrases like, “We’re too different” or “We’ve grown apart” or “Life has just gotten the best of us….” phrases that sound so innocent- yet are extremely lethal.

There are so many factors that can get in the way of a good marriage, but often, they are the small, unnoticed things that make their way in. In order to make sure our marriages survive and thrive, here are some relationship killers every couple should be on the lookout for:

1. Family

The number one relationship stress for most couples has little to do with their relationship and much to do with the relationships they are surrounded by. The role of your parents, in-laws, siblings, and friends all shift the moment you say “I do,” because when you join together as one, you’ve chosen to put your spouse above all others. Too many marriages are struggling simply due to a lack of priorities, finding themselves pulled by everyone else in every which way, except toward each other. Healthy marriages learn to choose one another above all others.

2. Lack of Communication

It’s true that the average couple invests in quality conversation only a few minutes a day. It’s easy to let life get busy and stop connecting with the one you love. But there’s no such thing as living in neutral, because drifting happens the moment we stop moving forward. Take the time to connect and communicate with your spouse often.

3. Stress

It’s so easy to take our stress out on our spouse. We can get into the habit of holding things in until we’re in the safety and comfort of our marriage - and then we explode. From financial problems, to illness, job-loss, and grief, healthy couples allow their stress to pull them together, by relying on each other, sharing it with one another, and carrying the load together.

4. Technology

I read a blog post about a guy getting a divorce…except this guy chose to divorce his phone. But it makes sense, because so many of us carry this dangerous relationship killer right in our back pocket. In the world of technology crazed, iPhone carrying, Facebook posting mania- it’s no joke that we find our time slipping away into the inanimate, instead of investing it into the intimate. Unplug, disconnect, shut down - and invest in your spouse. (11 signs you need a break from social media!)

5. Selfishness

Marriage is one huge, ongoing, life lesson in “unselfishness.” And we’ll either allow the experience to make us better, or we’ll grow bitter. Putting someone first is an incredibly hard task because our flesh is wired to choose self.
