"Ever hear of children growing up in abusive situations, who either grow up to be abused, or be an abuser?"
The term "abusive situations" covers too much ground to be useful. If one parent is abusing the children (beyond reasonable spanking, etc.) then it might be necessary to get the children away from that parent as a last resort, if an attitude adjustment doesn't do the trick.
However, unless there is something like that going on, indications are that children do better if the parents don't divorce.
"Gee, let's ask God about that..."
Always a good idea. Do you know what He has said about that?
It's not just physical abuse, there also can be mental and psychological abuse. I personally feel that men suffer from the later form more often than physical abuse. It is just as damaging as your head hitting a wall.
Psychological abuse is sneaky. The neighbors don't see it. Sometimes the abused person eventually starts doubting reality. It's called "gaslighting". The kids growing up under that kind of atmosphere will be irreparably damaged. Getting kicked down the hallway because you didn't move fast enough is bad, choosing whether to believe a parent or your own lying eyes, is just as bad.
I would really like to know why God lets this stuff happen. Of course everyone will answer for what they did in this world, but he also said something about millstones and harming children. It would be nice if some people got what was coming to them on this earth, instead of the next world...
For the record, I believe in reinstituting "fault" in divorce. Too many people are divorcing for trivial reasons, but OTOH, too many people never have to answer for bad behavior.
