7 Signs Your Boyfriend Might Be Cheating, According to a Mistress

A Mistress Reveals the Definitive Signs Your Boyfriend Is Cheating

No one wants to believe they’re being deceived, but sometimes, the red flags are too obvious to ignore. If you’ve ever suspected your partner of cheating, you may have wished you could get insight from someone on the other side of the betrayal.

Enter JeanMarie—one of SeekingArrangement’s most sought-after mistresses—who has seen it all when it comes to men hiding affairs. She shares the most common warning signs that a man is stepping out of his relationship.


1. He’s Lying (And He’s Bad at It)

If a man is having an affair, lies will pile up quickly. JeanMarie recalls dating a man who never spoke about his personal life—because he was married.

How to catch him: Pay attention to inconsistencies in his stories. If things don’t add up, call him out immediately—most cheaters don’t expect direct confrontation and may struggle to keep their lies straight.


2. He’s Making Large Cash Withdrawals

If he’s suddenly spending more money but you’re not seeing the benefits, he might be funding dates, gifts, or even hotel stays with someone else.

Why it matters: Many cheaters use cash instead of credit cards to avoid leaving a trail. If his ATM withdrawals have skyrocketed, it could be a red flag.


3. His Work Schedule Has Suddenly Changed

The classic excuse for cheating? “Work.” If he suddenly has longer hours, late meetings, or surprise business trips, he might not be spending that extra time at the office.

Warning signs to watch for:
✔ Frequent last-minute work trips
✔ “Crashing at a friend’s place” after a long night
✔ Always taking calls in private

According to JeanMarie, these are all go-to excuses cheaters use to cover their tracks.


4. He’s Less Interested in Sex

A sudden drop in intimacy could signal that he’s getting his needs met elsewhere.

JeanMarie’s advice:
✔ Try being extra affectionate—make his favorite meal, offer a massage, or plan a romantic night.
✔ If he responds positively, there’s still hope.
✔ If he avoids intimacy completely, it could mean he’s no longer attracted to you—or he’s distracted by someone else.


5. He’s Glued to His Phone (And Hiding It)

If he never used to care about his phone but now guards it like Fort Knox, something’s up.

Phone-related red flags:
New passcode on his phone (when he never had one before)
✔ Constantly checking notifications and hiding the screen
✔ Taking long, unexplained calls in another room

JeanMarie suggests searching his computer history or even setting up a fake social media profile to see if he takes the bait. If you go this route, don’t be a catfish—get a friend’s permission before using their photos.


6. His Appearance Has Suddenly Changed

Has he gone from sweatpants and a t-shirt to dressing like he’s on the cover of GQ overnight?

JeanMarie’s take: “Men are simple. Once they feel they ‘have you,’ they stop impressing you—and start impressing someone else.”

Of course, a new shirt or haircut doesn’t automatically mean he’s cheating, but drastic changes in style, grooming, or fitness habits could mean he’s trying to impress someone new.


7. His Behavior Feels… Off

At the end of the day, trust your gut. If he feels distant, avoids deep conversations, or acts defensive, these could all be signs that something’s wrong.

JeanMarie’s final advice: “Open your heart and realize everything happens for a reason.”

If you suspect something, don’t ignore it. Pay attention
