I'm Jewish and its the same with religious Jews. Sometimes they'll get married after meeting once. Its usually a few months tops of dating and then they'll be engaged and married within the year. With lots of babies to follow. They get married so young too, usually before 20. Yeah the divorce rates are low but is that because people feel pressured to not divorce because of the bible or is it because the women can't see a way out now that their purpose in life is to keep a happy house for her husband and multitudes of kids? I think Grace has too many aspirations to let herself go down that route, especially as her mum and sister have successful jobs.
