If you're currently plagued with anxiety about your other half's fidelity, you may be considering ways to prove or disprove your suspicions. In the modern day world, there are of course a number of technological advances that have made this kind of evidence irrefutable - such as video surveillance, for example. But while taking matters into your own hands can be an effective way to find out what you're dealing with, it's always best to try and tackle the issue with your partner before going behind their back. Although they will hopefully understand where your insecurities have stemmed from, if they are innocent, they may be offended by your distrust.
