Separation before a divorce. That's how we're told it should be, for the good of the society. Put simply, if you're considering to divorce your marriage partner, start from a separation and try to work out the differences.
In reality, iit hardly ever works.
Especially, if there's a lot of animosity and a great deal of publicity surrounding the couple. Just ask Paul McCarthy and Heather Mills...
So, what's the solution for an unhappy marriage?
Both, husband and wife should attempt to see marriage counselor first. Then, follow the advice. It well may be, that the counselor will come up with a solution far more doable than a separation.
