Carolina also knew and realized that she herself was neither a mother nor a really good wife. Whether it's for Antonio or also Dexter. But Carolina was just trying to live her days. She's just trying to make herself a worthy woman, in front of Dexter or her child.
Even though Dexter didn't really care about her, Carolina was just trying to be as independent as she could be. If indeed sometimes his life must go according to the will of God. In fact, Carolina did not want her life to end in vain in the city of New York.
And besides, Carolina also wanted to be a really useful wife to Dexter. And also he knew that no matter how much he refused, or didn't want it, in fact he was also trying to be a really useful woman, and not a useless woman to Dexter.
Actually, Carolina was just trying to be a woman that Dexter really wanted. But sometimes his life is not a life that can run according to his own will.
