Sometime it is best for the children when parents divorce, sometimes it can be a disaster, it all depends……………… but generally those kids, most, intend to have healthy relationship with there divorced parents after the divorce
about arguments, IMO, and I speak from long years of experience, IF there is a core established true out the years there is nothing wrong with an arguments, its a sign of a healthy relationship, we are talking about two individuals, characters, opinions and most often those opinions will very, hence comes arguments, I don’t know any family who doesn’t have arguments.
But when there is a fundamental difference becomes obvious, and then those arguments can turn into screaming nonsense and in some cases physical violence and all other options would fail, this is when divorce is "essential" for all parties, first and foremost for the sake of kids.
