If this is the type of situation you see yourself falling into, information is your most powerful assets.
Knowing for sure whether or not your spouse is a cheater can help you get through the difficult decision of whether to work things out with them despite all the difficulties, or to simply leave them so that you can devote your time to finding someone more worth while to have in your life.
Unknown numbers showing up on the caller ID at your residence, or in the call history on your cell phone bill, or in the recent calls on your lover's cell phone can be a source of a lot of stress, if you're not careful.
Believe it or not, the worst way you can go about dealing with this is to be confrontational.
In all likelihood, this will only cause the person you're in a relationship with to shut down, making communication with them even more difficult.
If you need a way of finding out information about these unknown callers quickly, and discreetly, getting a subscription to one of the many trustworthy reverse phone lookup service websites is the recommended solution.
At the very least, you can find out who you're dealing with, and if the nature of their calls to your spouse are worth your stress and concern.
There's no need to start a fight it is nothing to start a fight about, and understanding the situation before you woke headlong into an argument about something that may not be what it seems is the surest way down the path or regret.
With a simple reverse lookup query, it's easy to clear the fog, and get a little extra clarity in your life.
