I believe we need to put a different perspective on this topic and that is preparing children for marriage. Parents and Yeshivas need to take a more active role in better preparing kids for marriage. They need to understand that marriage is not disposable and that it takes hard work and commitment to make it work. It also takes a certain amount of maturity, wisdom, humor and the ability to compromise as well as putting your spouses needs first. That doesn’t mean that your needs are not important but when each spouse put’s the others needs first, everyone’s needs get addressed and satisfied.
The other thing that needs to be taught is what to look for in a spouse. How to recognize the qualities that are important to YOU (not necessarily your parents), but to you. Know what you are willing to compromise on and know what is absolutely non-negotiable.
If your child is prepared for dating in this manner then once you agree to a prospective shidduch you should be able to trust their judgment. However, anyone who is not ready or prepared to get married should not be dating or getting married just because everyone else is, that is a recipe for disaster not only for them and their spouse, but also for the potential children they bring into the union.
