It is nearly trivially true that most women who divorce wind up with replacement partners that are objectively (and usually subjectively too) inferior to the partner that they divorced. Sometimes they wind up with no new permanent partner at all.
They're almost always at a weaker position in the MMP/SMP than the first time. This effect is so strong that I can't think of any counterexamples off hand that I personally know. In many cases the delta in quality between first and second husband is truly profound.
But if you were to look at our mainstream entertainment, one would tend to conclude the opposite of this truth. Therefore, I'm putting out a request for propaganda...an RFP for those amused by that sort of thing...for artists, writers, etc, to present the world as it actually is, in a statistical sense. Hell, there's a good chance that a lot of women would even misinterpret your move as 'identifying with their actual problems', when you show the newly divorced woman with a couple of kids having a rude awakening in the SMP/MMP. I suggest doing this with secondary and tertiary characters, so you don't feel compelled to give them a happy ending, as it were.
