Study: It's not just millennials guilty of snooping on romantic partners

Most people know to keep their personal information safe from hackers or malware, but data shows a significant other is actually the person to keep an eye on.

A recent YouGov analysis found that about 37 percent of millennials read their partner's emails and texts, or snoop on social media, at least once per week without permission. About a quarter of those doing the snooping are at it every single day of the week.

And it's not just millennials — the same data shows that about 25 percent of adults ages 25-54 also sneak peeks at their partner's private information pretty regularly, too. It's only those baby boomers or older who tend to most often respect their partner's privacy, most likely because they're less accustomed to the digital age.

This raises the question, is new technology increasing suspicion and paranoia? Or were those baby boomers doing it too, but just with boxes of old letters from their exes? There's no answers on that yet, but the YouGov data did uncover a few other nuances of the digital age.

Breaking up with a significant other? Millennials reportedly are a third more likely to do it electronically. About 26 percent of people said they've broken up over the phone, and 14 percent said it ended via text message.

The social media snooping also extends to exes, with about 44 percent of adults saying it makes it harder for them to get over their old flames. About 9 percent of people surveyed — and 17 percent of millennials — said they look up their exes on social media at least once per week.
