Arabella realized that her husband had lived much even longer than she thought.
There were so many ladies he encountered to the extent that she concluded there was no point in getting jealous or insecure since she would only end up making herself crazy.
What was important was Ferdinand's love and attention was only on her now.
She had already told herself that in the past since she already had a feeling back then that contrary to Raymond and Alwin's belief that this was the first time Ferdinand fell in love, she had a feeling it wasn't.
Arabella reminded herself once again that the present and the future were what matters as a lot of pretty ladies she did not know about crossed Ferdinand's mind as he pondered if he had fallen in love before.
Some he could not recall clearly, some he does. And he finally understood that there were those who fell for him, but he did not notice back then.
