I think that latter part really does ring true. No matter the sexualities of the people involved, we've all felt the shift when a close friend marries or enters into a coupled domestic arrangement--and the almost inevitable loss of intimacy with the friend. And, unless he really alienates them, no doubt he will be asked to be godfather to at least some of those toddlers! That might make for an interesting show.
Coupling certainly isn't the only path in life, but the social messages that suggest it is are undeniable powerful.
