Maybe they want to understand why their spouse has chosen to break things off instead of working on their marriage. Maybe they want to know if what they’re going through in their marriage is worthy of a divorce. Or maybe they’re just curious about why people divorce in general. If you’re asking yourself, “Should I get a divorce?”, then there must be something going on in your married life that’s making you doubt everything. Whatever your motivation is for looking up the reasons people decide to call it quits and go through the difficult divorce process, you’ll find both research-based answers along with surprising ones about the causes of divorce. RELATED: Dear Sh*tty Husbands: This Is Your Wake Up Call Researchers interviewed 52 divorced individuals who had received the Prevention and Relationship Enhancement Program (PREP) while engaged. In 2013, they presented their findings.

Here are the top 5 reasons for divorce, according to research:

1. Lack of commitment

According to the research, the number one reason people divorce is a lack of commitment. This means that at least one spouse stopped making their marriage a priority. When a spouse decides to stop making a daily commitment to have a great relationship, misery follows. For some couples, the estrangement happened gradually. They drifted apart until one of them was unwilling to continue living with an unfulfilling marriage. For others, it was an abrupt change due to negative outside influences.

2. Infidelity

One of the negative outside influences that can lead to a lack of commitment is the second major reason the researchers found couples divorced: infidelity. Infidelity is painful and changes both the betrayer and the betrayed. Some couples use infidelity to create stronger relationships. However, others find the betrayal of infidelity and/or trying to repair their relationship too painful and choose divorce instead. RELATED: My Wife Divorced Me Because I Left The Dishes By The Sink

3. Too much conflict

Over half of the individuals interviewed for this research cited too much conflict and arguing as a major reason they divorced. When a couple has poor communication skills, it’s hard to resolve disagreements calmly or effectively. When disagreements are regularly left unresolved, it’s common for resentment to build. It’s also common for feelings of positive connection and mutual support to diminish. Without effective communication skills, these negative results can spiral into a lack of commitment and divorce.

4. Married too young

Age does have something to do with the success of a marriage. The data suggests that when couples wed with at least one spouse in their early 20’s or younger that they’re more likely to divorce. Some of the study participants reported that they had only known their future spouse a short time before marrying. Many of those who married too young, also wished they had dated their future spouse longer to either gain a better perspective on the relationship or to make a more rational decision as to whom they should marry. Some participants who stated that marrying too young was one of their major reasons for divorce also stated they were too young to make mature objective decisions about marriage.

5. Financial problems

Of the study participants who reported that financial problems were a major contributor to divorce, many said it wasn’t the main reason. Instead, the financial difficulties added stress and tension to their relationship. Interestingly, other participants stated that their financial problems were due to other issues like health problems, substance abuse, and infidelity.

The others that the study uncovered, in order, were substance abuse, domestic violence, health problems, lack of support from family, religious differences, and little or no premarital education. What’s interesting to note about this study is that it was conducted after the divorces were final and that these reasons for divorce were typically the deeper reasons and not necessarily the last straw that led one of the spouses to file for divorce. But these aren’t the only reasons couples divorce. There are all kinds of strange, sad, and frightening circumstances that can play into the decision to call it quits.
