Recently, our daughter (17 in June) told my wife and me that she has started dating not 1, but 2 guys. No introductions needed since we already know them; they’ve been close friends of hers for quite some time now. Daughter put it as: why do I have to choose if I like them both and they don’t mind sharing?
I just don’t like it.
The problem with the statistic you cited is that it counts second, third, etc marriages as well. Second marriages are more likely to fail as it is clear people who have already had a divorce are just bad at being married. Which is proof in itself that changing partners isn’t good.
By that logic, a spousal abuse victim is much better off staying with the abuser because “changing partners isn’t good”.
