Adultery is voluntary sexual intercourse of a married person with someone other than their spouse, according to Black’s Law Dictionary. Infidelity simply means unfaithfulness, which could technically include adultery.

A Texas A&M study released in September found that husbands tend to cheat more due to stronger sexual impulses, not necessarily a lack of self-control. Meanwhile, the number of cheating wives has increased by nearly 40 percent in the last 20 years, according to the National Opinion Research Center.

The gender gap for cheaters is closing, while the sanctity of marriage is dissipating across the board. There’s probably been a time or two (or three) that you’ve suspected something was going on behind your back. Whether sexual activity is non-existent or your partner’s not meeting your needs, it’s best to find out for certain than torture yourself with speculation. There are several ways you can discreetly discover the truth and stop wasting away years with an unfaithful individual.

Private Investigator

Your Lifeshield wireless security can catch a cheating spouse if they have the audacity to do the deed in your own home. Otherwise, you’ll need to hire a private investigator. This is the most expensive option available, but it will likely yield the best results.

Private investigators (PI) are licensed by your respective state and trained in various methods of surveillance and forensics. Advanced Surveillance Group, a nationwide network of private investigators, uses methods such as vehicle tracking, computer forensics, asset searches, and Internet activity tracking to uncover infidelity. Though the NSA gets most of the attention as far as data farming, private companies such as Lotame and Sqrrl Data do the exact same thing. Some PIs form relationships with these companies, which assist them in tracking virtually every online move of the suspected cheater.

The biggest advantage of hiring a PI is that you’ll have hard evidence of infidelity if you decide to pursue a divorce. Hearsay generally will not cut it in a divorce case and could ultimately result in an unfavorable outcome for you. The only major deterrent is cost. PIs charge an average rate of $50-$55 per hour, with some charging up to $300 per hour. Infidelity cases, depending on the level of difficulty, can sometimes require a retainer fee up to $5,000, according to PInow.com.

Remember, you must tell your PI everything about your relationship, no matter how painful it may be, in order to ensure the best results.

Home Lie Detector Tests

A much less expensive route would be to purchase USB polygraph software. Despite mixed reviews, one company claims 80 to 99 percent accuracy when the software is used correctly. Kits come with pulse finger clips, a breathing apparatus and the CD-ROM containing the polygraph virtual machine. It’s a bargain for around $100.

Mobile Apps To Track Cheaters

Sadly, hundreds of smartphone apps actually aid cheaters in adulterous endeavors. But there are also apps available for people who want to track a suspected cheating spouse. In a matter of full disclosure, some of these apps are a little disturbing and can potentially violate privacy laws, so use your best judgment.

“Rastreador de Namorados,” which is Portuguese for “Boyfriend Tracker,” made waves in Brazil before Google removed it from its app store this past summer. The functionality was quite impressive. The app would send you live GPS location data of your spouse. It also duplicated and forwarded all text messages they received. A similar GPS-tracking app called “Track Your Wife” is currently available in the Google app store. Footprints is the iPhone equivalent app.
