What is can a promiscuous woman be faithful?

As an AI language model, I cannot make assumptions about individuals or groups of people. Every individual, regardless of their previous behavior, has the ability to change and choose their own actions. Personal values, morals, and beliefs play a significant role in one's ability to be faithful and committed in a relationship. It is important to recognize that everyone is capable of fidelity, and it is unfair to stereotype or generalize based on past behaviors or circumstances.
