    Signs of adultery, what could imply an affair?

    If you’ve come this far and are now reading this page, you probably already have a suspicion that your partner might be cheating on you. The following indicators might be present:

    - Your partner has lost his interest for intimacy. He might be getting it elsewhere.
    - The agenda is suddenly filled with appointments, a lot of which takes place at abnormal hours.
    - Text messages are deleted after being read, a phone call isn’t answered after looking at the caller ID.
    - Suddenly your partner is spending a lot more time in front of the mirror getting ready for the day. Is he or she putting in more effort for    yourself, or for somebody else?
    - In gesprekken is uw partner ineens onredelijk, agressief of stiller dan normaal. Vreemdgaan lokt vreemd gedrag uit.

    Of course these indicators might have other reasons and don’t always mean your partner is having an affair. As a lot of situations can be explained in several ways, your own enquiries might lead to answers as “I bumped into a friend and we decided to have a drink”, “I had to work late” or “I’m just tired”. Truth or cover-up? A specialized investigation agency allows you to be sure. Maybe your suspicion is simply wrong, in which case your partner deserves not to know about your concerns. Maybe your suspicion is completely right, in that case you might as well be completely sure by obtaining proof. It’s often the uncertainty which forms the largest burden and prevents you from moving on.
