A radical change in sex life may be hiding something.
- A disinterest in the relationship

Why is this a sign?
When a partner has an affair, they may become emotionally detached from their primary relationship.
Examples:
- He no longer shows interest in your day.
- He avoids serious discussions about the couple’s future.
- He seems physically present but mentally absent.
If your partner seems distant, their heart may be too.
- Evasive and vague answers
Why is this a sign?
A cheating partner needs to withhold information, so they adopt vague and imprecise communication.
Examples:
- He always says “nothing special” when you ask him how his day was.
- He changes the subject as soon as you bring up his schedule.
- He becomes irritable or evasive when you insist.
If your questions remain unanswered, be on your guard.
- A defensive and aggressive attitude

Why is this a sign?
In cases of infidelity, one partner may feel guilty. The result? They become more nervous and may overreact to accusations, even implied ones.
Examples:
- He gets angry as soon as you bring up the subject of fidelity or infidelity.
- He accuses you of being “too jealous” for no apparent reason.
- He suddenly becomes defensive, even when asked a trivial question.
An overreaction often hides an unacknowledged truth.
- Suspicious spending
Why is this a sign?
An affair often leads to unusual expenses: restaurants, gifts, hotels, travel, etc.
Examples:
- You notice some strange bills on his bank statement.
- He withdraws more cash than usual.
- He suddenly refuses to share his accounts with you.
