Going on vacation is a time to relax and unwind, but it can also lead to mistrust and insecurity in relationships. In this case study, we share the story of Mark and Emma, a couple who experienced this first-hand after their trip to Valencia. We helped them resolve their issues with the use of a polygraph test.


Mark and Emma had been together for nearly five years and were living in the UK. Their busy work schedules left little time for exercise or healthy living. They booked a holiday to Valencia, which Emma planned in detail, including her wardrobe for the trip. However, Mark became increasingly paranoid about other men admiring Emma’s appearance and became jealous of the attention she received.

During the vacation, Mark and Emma had a massive argument, which resulted in Emma leaving to stay in a friend’s apartment. Mark got drunk and woke up with other people in his room. The incident led to deep mistrust, and they decided to take a polygraph test to resolve their issues.

Polygraph Test in London

Mark and Emma visited our office in London for the polygraph test, which examined whether they had any sexual contact with someone other than their partner during the vacation. Emma passed the examination, but Mark failed. At first, he contested the results, but eventually, he admitted to having “revenge sex” with someone he met while Emma was out for the night.


Although the test results were painful for Emma, she was relieved to know that she had been faithful. Mark’s infidelity caused significant distress, but he apologized and explained his reasons. He later discovered that he was going to be a father, which motivated him to start going to the gym regularly.


Vacations can lead to mistrust and insecurity in relationships. Mark and Emma’s story highlights the importance of honesty, trust, and communication in any relationship. Our polygraph test provided the clarity they needed to move forward and start the healing process.
