Private investigators have identified behaviors that may indicate your partner is being unfaithful, including a sudden interest in a particular household chore.
Research indicates men are statistically more likely to cheat than women. A study by the Institute of Family Studies found that 20 percent of married men have been unfaithful, compared to 13 percent of married women.
The 2018 report also highlighted that among married individuals who had cheated, 40 percent were either divorced or separated at the time of the study.
While catching your partner in the act is a clear sign of infidelity, there are other indicators that may suggest cheating.
Professionals have compiled a list of common behaviors that might signal infidelity.

If your spouse typically does their own laundry, it’s likely no cause for concern. However, a sudden urge to do it without reason might be more telling.
UK Private Investigators state: “If your partner, who has never shown much interest in doing the laundry, suddenly starts insisting on washing their own clothes, this could be a red flag.
“If they are cheating, they may be worried about things like perfume, lipstick marks, or stray hairs on their clothes, and doing their own laundry allows them to hide these signs without you noticing.”
A noticeable increase in your partner’s car mileage without a plausible explanation may indicate detours for extramarital activities.
“A change in mileage that doesn’t match up with your partner’s usual routine or work commitments can be another subtle but telling sign,” the investigators explained.
“If they claim to have been nearby, whether they said they were at work later than usual or at the gym, a large increase in mileage that doesn’t match up with this may indicate secret trips to meet someone.”
Unexpectedly low mileage might also raise suspicion, suggesting they may not be traveling as far as claimed.

While everyone deserves privacy, a sudden increase in secrecy could be cause for concern.
Professionals caution: “Changes in privacy on your partner’s devices, like a new password, locked apps, or logging out of shared devices like a laptop, can suggest that they are hiding something.”
Global Investigations research shows secretive phone habits are frequently linked to infidelity.
If your partner makes a significant purchase, like a $200 expense at Macy’s without an occasion, it could indicate infidelity.
“Things like unexplained expenses, hidden purchases, or unusual cash withdrawals can sometimes be a sign that your partner is being unfaithful,” experts note.
“Whether they are buying dinners, gifts, hotel rooms, or transport, people having an affair tend to spend more money than usual.”

If your partner suddenly takes an unexpected interest in their appearance, it could be a red flag.
“A sudden, unexplained effort to improve appearance, such as new clothes, changes to their hair, or increased time at the gym, might be a sign of trying to impress someone new,” experts from the PI agency suggest.
“While self-improvement and taking pride in their appearance isn’t suspicious in itself, it can be a red flag when they don’t tell you what their motivation is, or if they don’t show interest in your opinion or attention following the changes to their appearance.”
