As I've interacted with couples from all over the world, I've found that many of the issues that ultimately lead to infidelity and divorce happen by accident. People don't usually set out to sabotage their marriage and wind up in divorce court, but small choices can ultimately lead to big disasters. Subtle poor choices along the way can pile up like a snowball rolling down a hill until it's big enough to start an avalanche of consequences.

Below are seven of the most common ways people can harm their marriage (sometimes without even realizing it). Avoid these and you'll be safeguarding your marriage.

(In no particular order):

1. Not wearing a wedding ring

People might just not be into jewelry or not think it's a big deal, but wearing a ring can be a first line of defense against adultery.

2. Digital distractions

Sometimes I give my iPhone more attention than I give my wife, and that can't happen! Do your best to keep screens turned off as much as possible when you're together with your spouse. Talking with your spouse is always better than texting with somebody else (or playing Candy Crush, or checking facebook, etc.).

3. Inconsistency in parenting

Raising kids is one of the most sacred duties on earth, but it can also harm your marriage if you don't have a unified approach with your spouse. Ashley and I don't argue much, but many (if not most) of our disagreements have come out of miscommunications about parenting.

4. Flirting

This one is two-fold, because we harm our marriages when we STOP flirting with our spouse or when we START flirting with anybody else! Flirting within marriage is always helpful, but flirting outside of your marriage is always harmful!

5. Porn (and/or graphic romance novels)

Many couples think porn is a harmless fantasy that can actually spice things up in the bedroom if they watch it together, but the truth is that porn is an enemy of real intimacy.

6. Autopilot

Cable TV companies give their best rates and service at the beginning but then treat you much worse after the "promotional period" expires. Sadly, many marriages look like this. We give each other our best at the beginning of the relationship, but then get into "autopilot" and stop giving each other our best.

7. Negative friends

Your friends have the unique ability to encourage your marriage or to discourage your marriage. Make sure you're hanging out with people who love you AND love your spouse. Choose friends who will strengthen your character and remove yourself from people who would tempt you to compromise your character.
