He nodded, swallowing the bitterness of his regret. “Give me some privacy. If you would, please.”

She did not look at him as she left.

Isabel stepped out of the fitting room, and closed the curtain behind her. Her hands shook terribly, incited by the sight of Gray’s body as he dressed and undressed, teasing her with his male perfection.

He was in the prime of his life, retaining the power and strength of youth, while adding the maturity of tough times and a few years. He rippled with muscle everywhere, and she knew from being held against him yesterday that he wielded that power carefully.

Honestly, Gray. You are too young for me.

Why had she not stayed the straight course? Looking at him now, seeing all of his vigor and vitality, Isabel collected how wrong she had been to bind his life to hers.

He needed a lover to take up his time and attention. A man of his age was bursting with lust, and the primal desire to sow his oats. She was convenient and attractive, and so he wanted her. She was the only woman he knew, for the time being. But one does not have an affair with one’s spouse.

Isabel groaned inwardly. God, why had she married again? She had made the ultimate commitment to avoid commitment, and look where that foolishness had landed her.

Men who looked like Gray were not constant. She had learned that lesson with Pelham. The dashing earl had needed a wife, and he’d lusted for her. A perfect combination in his mind. But once his infatuation had faded, he had moved on to the next bed, completely disregarding how in love with him she was. Grayson would move on as well. Certainly, he was more somber now, more grounded than when they had wed, but his age was undeniable.

Isabel could bear the rumors of his sexual prowess, and the innuendoes that she was too old to satisfy him or provide him an heir, as long as she felt no claim to him. She was faithful to her lovers, and expected the same in return for the duration of the affair. And therein lay the rub. Affairs were meant to be ended, while marriages lasted until death.
