A lot of couples are saying “I do” – but only for about 30 years max! New statistics show a surge in couples divorcing after 20 or 30 years of marriage! And, contrary to popular belief, it’s usually not because of an affair. Instead, long-married couples usually split up because an issue has been building up and festering for literally decades – and finally reaches a breaking point.

The second most popular reason a lot of long-married couples divorce? As clichéd as it sounds, they grow apart! Some relationships have been going downhill for decades and finally lose all their steam. The marriage doesn't blow up, it's more like a car tire that’s been leaking air for a long time. After a while, it's totally flat. Experts say, a lot of times, it happens when the relationship is out of balance. Like one partner is a workaholic, and the other is more focused on family. They end up building separate social networks, and, eventually, end up living totally separate lives.

Experts think the trend will only get bigger, since we’re living longer than ever. After all, people in their 50s have at least 30 good years ahead. And they want to enjoy it – instead of soldiering on in a bad marriage like previous generations. That’s because the Baby Boomers were the originators of a higher divorce rate - and experts are predicting a spike in older couples divorcing in the coming years.
