If you've searched your sweetie's Internet browsing history, made up a fake MySpace profile to check up on him or hacked into his e-mail, you're totally normal!

So says a U.K. study, which found that 70 percent of people regularly snoop on their partners online to see if their loved ones are surfing porn sites or exchanging racy pics with the office secretary. What's worse, the study, commissioned by people search engine yasni.co.uk, reported that 54 percent of people then accused their lovers of sneaking around after finding photos of them with opposite-sex friends.

U.S. couples are cyber-sleuthing on their SOs, too. More than half of 18- to 29-year-olds said they would seize the opportunity to snoop, according to ALK Technologies -- a New Jersey-based company that sells software that turns cell phones and PDAs into satellite tracking devices. If you don't think GPS-ing your guy is creepy enough, you can now also snoop via cell phone as well as using sites and software to catch him in the probably imaginary act.

Be Prepared for What You Might Find
Kat from California says she doesn't check up on her husband's online activity, but has in the past.

"When I was having stalking issues, I checked out his e-mail to see what a friend of mine sent him after she mentioned casually that she e-mailed him with a 'don't tell her, I don't want her to worry' sort of thing. I'd have to say, if one is a snooper at heart, they're either looking for trouble or they have trust issues."

Jodi discovered her ex-husband's affair through a joint AOL account. After that, she became a full-time snoop.

"Once I became aware that he was carrying on conversations of an 'adult' nature with another woman, then his e-mails became public information. Up until then I totally respected his privacy and never looked at this e-mail account. Once that trust had been broken, it became my business, and I discovered his affair had been going on for well over a year."

Speak Before You Snoop
Counselor and relationship expert Melody Brooke, MA, LPC, LMFT, author of "Oh Wow This Changes Everything," says people who snoop obviously have trust issues. Even if they are warranted, the couple needs to talk about the suspicious behavior or cheating.

"No matter what the cause, snooping is a symptom of something awry in the relationship," she says. "If you don't trust your partner, you need to work on why you don't trust them. That can be within yourself, or within your relationship. The problem is not the snooping, but the lack of trust it implies. Communication about that insecurity is the only way to begin to shift the fear that drives the behavior."
