If you have the notion that your spouse is being unfaithful to you, then consider using Spokeo's High Powered Search Tool to find total proof that they're doing it.
Because most affairs take place with someone unrelated to the relationship (ie: most cheating spouses find complete strangers rather than people who might be connected to them in some way), the average partner will probably use the internet to find an extramarital relationship. That said, if you suspect a partner is cheating, they too are most likely using the internet to do it. The most likely resource they will be using is the plentiful number of Dating or Hookup sites available online. Spokeo can effectively track your partner or spouse's name appearing on such websites, which will definitively proof whether they are engaging in or seeking to engage in an extramarital affair.

If you enter your partner or spouse's e-mail address, Spokeo will search online for all instances of that e-mail address showing up. Because people tend to use the same e-mail addresses and usernames for everything (or very simple variations of the same one), just typing in an e-mail address can show you a whole side to your partner that you didn't know existed. Spokeo accounts for the subtle numerical differences which occur on the internet, so just typing in your spouse's e-mail address could net you a whole bunch of information related to their involvement with online dating sites. No matter what website it shows up on, Spokeo will gather it and show it to you in a user-friendly way.
Furthermore, you can enter the telephone number of your partner or spouse. If this information has ever occurred online, you'll know about it, meaning you can see every place online that your partner or spouse has posted their phone. Most people do not share their phone numbers online, but since Spokeo categorizes every website it locates the information you're searching for, you'll know every kind of website that your spouse has shared their phone number.
If you know your spouse or partner's frequent use name, you're in the gold and should have no problem at all finding out what they're doing online. Just type that in, and you'll see all places where that username has also occurred. People rarely create a new username for every type of website they wish to make an account for. It would just be too inconvenient to try to remember all of that information. Instead, most people stick to one screen name for the majority of their lives and use that for every site they sign up for. If a partner is cheating, they probably assume that no one will attempt to use a high-powered search engine to track their behavior. This is why Spokeo is such an effective tool for catching a cheating spouse.
If Spokeo proves ineffective, there are alternatives for catching a cheating spouse. Another effective tool for this method is Cell Phone Spying, which involves installing a program on your partner's smart phone which then uploads all of the information it gathers to a website that you can access. For this information I recommend SpyBubble. To learn more about SpyBubble, http://www.spybubblespy.info
