I actually would like to be proved wrong here so it’s not a provocative title, but I do think it’s something of a myth that children would like their parents to divorce and to live apart.
My own experience is that when this happens parents move on to new relationships quite quickly and this is confusing and difficult for children. Then obviously there’s financial considerations and practicalities (living in two homes.)
I’m obviously not talking about relationships that must end because of abuse but the sort of gone stale relationships where parents are urged to split because the children will want it.
