Final answer:
The information provided does not mention Bob from Seattle or his conversation with Aunt Madina, so we cannot determine the exact length of time they talked before getting married.
Step-by-step explanation:
The question is asking about the duration of time that Bob from Seattle talked to Aunt Madina before asking her to get married. This question is not directly answered in the provided information. None of the given passages specifically mention Bob from Seattle or his conversation with Aunt Madina. Therefore, we cannot determine the exact length of time they talked before getting married.
