I think that this piece can be best summed up as "marriage isn't fulfilling for a self-absorbed, stuck-up jerk."
Ultimately, most modern takes on marriage or family or whatnot always seem to end with the author suggesting that marriage is an outdated institution that needs to be changed to be less permanent, and if children are involved seem to suggest that we reallly would be better off if parents didn't bother to raise their children so much and let the society, daycare, and schools do more of the heavy lifting (although Ms. Loh's doesn't touch as much on the subject of children).
Ultimately, all of these things seem to come out of the convicion of the author that she (or occasionally he) is the most important person in the world and that the overweening purpose of her life is to be entertained and fulfilled. Children, spouses, pets - ultimately nothing else must get in the way of their bliss.
I confess to somewhat have some of the same personality tendencies myself; but then again, that is why I'm still single, because I'm smart enough to realize that until I mature enough to do so, I should not take on the responsibility of a marriage -or, for that matter, a serious relationship.
(And before anyone thinks that I am advocating a "free love" lifestyle, I am also a virgin).
That is all.
