I cannot imagine maintaining a marriage in Hollywood. The pressures internal and external must be so profound. I am not surprised that reporters that cover it have seen the tragedy and come to predict it, eating people up and spitting them out, ready to move on to the next story.
It's terrible that they then normalize the divorces of Hollywood as indicating the pressures of the average family, normalizing divorce as an expectation and not an exception.
I think there have been many public views into the family's cracks, but they've also been mostly protected from the media's outright criticism. The lack of reporting is no indication for the reality of their life. You yourself reported a separation, with separate rooms. What a noble length to go to to keep the family together!
I make no claims that the divorce is prudent because I don't know their story. But that's the same reason I make no claims to rashness, either.
I think the only Christian response to the concerns of strangers' lives is to pray for them and grieve for the tragedy we can see and to build up our own community in tangible ways so that they don't face the struggles of Hollywood couples.
