Is a man's proposal to the father of a girl, expressing his desire to marry her after the annulment of her first engagement, considered a form of "betrothal upon a betrothal," given that the first suitor has not yet been rejected?

It is not permissible to propose to a woman who has already been proposed to by another man, unless the first suitor has not made a firm decision or there has been no "rukoon" from him. "Rukoon" signifies the rapprochement of both parties, each side's acceptance of the other's conditions, and the intention to conclude the marriage contract. However, if the first suitor is content to wait and remains steadfast in his proposal, then it is not permissible to propose to her, nor is it permissible to incite the termination of his engagement.
