Pac-Man: Ok, if Hashem wants them to get married at 18, shouldn’t they be married at 18? The Gemara says 40 days before the vlad is born a bas kol goes out and says Polni ben Polnis will marry Polnus bas Polnis and the shidduch is born. All that needs to happen is these two people need to date and get married. So if hashem wants them to get married at 18, they will need to meet when they are 18. If hashem wants him to be 23 and she should be 18, that is when they will meet. If he needs to be 35 and she 30, that is when they will get married.
In other words, there is really no shidduch crises. People are getting married when Hashem WANTS them to get married. Unless you feel today’s generation are all not marrying their zivug and that is why 23 year old boys gate 18 year old girls.
