From reading the article, it appears that each spouse has put their children from prior marriages first in priority. I feel this to be an appropriate response.
This is the death knell of modern day 2nd marriages. "Putting the children first" has taken on a new and flawed meaning as children call the shots over adults and virulently play divorced parent against divorced parent against stepparent--carefully choosing which adult will BEFRIEND them rather than parent them.
Putting the children first means having their best interest at heart. Lovingly and FIRMLY guiding them where the adults call the shots (aka living a married life under one roof). The government has equated all correction of children as "abuse" therefore you see parents playing "step 'n' fetch" to their own children. You can even see this in Barry as he was one of the earlier "single parent familes" (TM) where the child is coddled, spoiled and given ZERO expectations/standards.
That being said, as a single woman, I would NEVER get involved with a "previously enjoyed family" for just the reasons I mentioned above. The bitterness of the modern day mother against her ex-husband and the constant befriending of her children is a set up for failure for any second wife.
