Discovering your partner has cheated is never easy, but most of us would rather know the truth than remain in the dark. But are there clear signs of a cheating spouse to look out for?

If you ask a private investigator, that answer is a resounding YES! In fact, many people turn to the experts to catch a spouse in the act or confirm suspicions. As the ones that are paid to hunt down cheaters, private investigators know all of the signs that indicate someone is hiding something – or someone. Here are six of the most common indicators.

1. An altered schedule.
   If your partner suddenly needs to work late multiple times per week, and it starts happening more often, it could be a red flag. Excuses like work meetings, traffic jams, and piles of paperwork are only believable for so long – especially if this behavior is out of the blue.
2. Difficulty reaching them.
   If you’re being cheated on, your significant other will probably be less likely to answer your calls or respond to your texts. If there are periods of time when they’re unreachable (especially while working late or on a business trip), that’s a bad sign.
3. New focus on physical appearance.
   If they start eating healthier and exercising seemingly out of nowhere, it could be a sign they’re trying to appear more attractive to someone else. If they also have a renewed focus on shopping for new clothes, visiting the hair stylist, or other wearing attractive scents.
4. Unexplained spending
   If you see strange charges on your partner’s credit cards or there’s suddenly less money in your shared or individual financial accounts, it could be a sign of infidelity.
5. Their friends seem uncomfortable around you
   A cheater’s friends often know what’s going on before the victim. If you notice their friends acting strange around you or flat-out avoiding you, this may be why.
6. Changes in your sex life
   Significantly less, more, or different sex in your relationship could be a sign you’re with a cheater. Less sex occurs because your partner is focused on someone else, more because they’re overcompensating, and different because they’re used to a new sex partner.

One of the strongest signs of a cheating spouse is your own intuition. Chances are you know when your partner isn’t being 100% truthful, so trust your gut. Also know that your spouse may exhibit all of these signs and not actually be cheating. In this case, the signs point to something being off in the relationship. If you want to know for sure if they’re cheating, hire a private investigator.
