This is a really interesting article by the Independent looking at four typical negative relationship behaviours that when they coincide, more often than not, statistically lead to divorce.

From a divorce lawyer's perspective, I see many of these behaviours perpetuate after divorce, leading to messier, more confrontational and therefore more expensive proceedings. 

Therefore, not only should this article be a word of warning for those looking to save their relationship, but also those who have already separated, and want to resolve the division of their marital assets and disputes over children with minimal confrontation and expense.
