See Reha I agree that that most people don’t observe that theory in real life and alot of people are out to date just for the sake of it … but thats the same with marriage too you have these abusive partners in a marriage who do not know how to treat a significant other (again life1 has many examples). If these people would have dated and gotten their behind dumped a couple of times because of this crap then they would learn how to treat a sig other. On the flip side of the coin you have these amazing people who were the best gf/bf and got dumped and took a complete U-turn.
The point I am trying to make is that you can’t really say one way is better than another. Both have their negatives and positives and it pretty much comes down to a personal choice. Now if you bring religion in then it gets skewed to one side a little but even Islam gives us a choice to marry someone we like (not necessarily date). So if its coming down to personal choices then I personally would prefer to get to know the person a little bit better before getting married. Thats my two cents
