Private investigators reveal 5 signs your partner might be cheating including one common household chore

Private investigators have revealed the signs that could signal that your partner is being unfaithful, one of which includes them all of a sudden taking an interest in a specific household chore.

Statistics have shown that men are more likely to cheat than women. One study by the Institute of Family Studies found that 20 per cent of married men have cheated, while 13 per cent of women had.

The 2018 report also stated that among the married adults who had cheated on their spouses before, 40 per cent at the time were divorced or separated.

Of course, if you actually catch your partner in the act, then you know that they're being unfaithful; but there are other ways you might be able to work out if you're being cheated on.

Experts have put together a list of some of the common behaviors that signal someone's cheating.

Sudden interest in doing their own laundry

Your spouse might already do their own laundry (hello smelly gym gear), and if this is the case, it's unlikely to be anything to do with cheating; it's more likely if they suddenly start doing it for no apparent reason.

Experts at UK Private Investigators said: "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."

Unexplained mileage on their car

If your partner's mileage is much higher than usual, it could mean that they've been taking diversions for their 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 said.

"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."

Lower than expected mileage may also be a sign. For example, they may say they're driving to another city for work, but they're actually hooking up with someone locally.

New password protections

Of course, everyone has the right to privacy, and your partner may have always been a private person, but if they're clamping down on what you can access randomly, then it can spark suspicion.

The professionals say: "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."

According to research from Global Investigations, secretive phone habits are among the most common signs of infidelity.

Changes to spending habits

Has your partner forked out $200 at Macy's even though it's months until your birthday? This kind of behavior can also signal that your spouse is seeing someone on the side.

"Things like unexplained expenses, hidden purchases, or unusual cash withdrawals can sometimes be a sign that your partner is being unfaithful," the experts say.

"Whether they are buying dinners, gifts, hotel rooms, or transport, people having an affair tend to spend more money than usual."

Changes to their personal appearance

Is your wife suddenly hitting the gym five times a week, or does your husband now want to jet to Turkey for a hair transplant? Changes like these are possible red flags.

Experts from the PI agency shared: "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.

"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."
