Common Signs of a Cheating Partner

There are innumerable indicators of possible infidelity. Of course, your partner or spouse displaying any of these qualities won’t necessarily mean they are cheating, but overlapping instances of any of the following could give you some clues as to their duplicitous character:

  • Changes in appearance and grooming habits: Intimate undergarments that don’t match the occasion.
  • Sudden increases or decreases in intimacy: Going out of their way to display an excess of affection could be an indicator of compensating for infidelity.
  • Inconsistencies about their whereabouts: Your partner says they were at their bestie’s place last night, yet when that same close friend bumps into you in town they mention that they haven’t been spending any time with your partner at all lately.
  • Secretive about their online activities: Meticulous attempts to obfuscate their browser/search history or online communications could be an indicator that they have something to hide.
  • Peculiar work schedule: A sudden propensity to “work late” or participate in numerous “work related social events”.
  • Your partner is defensive when you ask about their whereabouts or unavailability: An almost aggressive need to avoid the topic when pressed on their whereabouts is a dead giveaway that something is amiss.
  • Mysterious credit card charges and call logs.
  • Uncharacteristic eagerness to run errands: Picking up items you already have enough of or spending unusual amounts of time running those errands.
  • You can tell something is off: This is the most important sign. Obviously you could be wrong, but the greatest indicator of possible infidelity has often been our clients’ instincts on the matter.
