When a married man is attracted to another woman, he does these nine things:

Suddenly more affectionate attitudes.
Attempts to compensate.
Unexplained mood swings.
Guilt often manifests itself irregularly.

9. Justify your behavior

If asked, he can downplay everything:

“You’re exaggerating.”
“It’s nothing.”
“It’s just your imagination.”
Avoid going into detail and try to close the topic quickly.

What all this really means:
Not all of these signs necessarily indicate infidelity.

But they can reflect something important:

an internal conflict that is not being expressed.

It could be attraction, curiosity, dissatisfaction, or simply a stage of change.
