Well, yes that was depressing. I agree that it was missing the obligatory divorce also.
Then we could see that "seeking exciting romantic partner" aspect (which follows the settling for domestic compatibility to procreate aspect). Then the woman can flit around in inappropriate clothing and posture and flirt with the next guy. There will be concerts, camping and BBQ's, followed by cohabitation, boring proposal and another wedding featuring photographs with everyone straining their facial muscles to look like excited smiles.
Oh, don't forget, everyone has their children act as participants in the wedding ceremony: ring bearer, flower girls, even bridesmaids and groomsmen! (No matter they are under the age of 12!).
This is marriage and life without God. Period.
