Dating courtship absolutely
This ensures that hearts are not too invested beyond repair, and that both persons are able to become available to new persons.
They are not going into courtship with any thought that it is not the one. It is quite a big step to become formally exclusive with someone.
It risks giving in to the temptation to do that one thing reserved ONLY to married couples because you become so used to each other and, what the heck, you love each other and are practically married anyway, so why not?
At the practical level, you want to be in courtship for a short time, with the agreement to get engaged or end the relationship at the end of that time period.
There is a fundamental different between courtship and dating.
Dating does not necessarily mean the persons are interested in marriage at all, let alone interested in determining if this person they are dating might be the person they should marry one day.
