That depends on many things. They may stay together for their children, so that the kids don't have to make a lot of choices such as: who's house do we stay at, how long do we stay at each house, who gets custody, who gets to claim them on their income taxes, etc etc. People might want to avoid all the hassle of getting a divorce. There can also be an emotional side to it, for example some parents might think it sets the worst possible example of marriage to their children if they get divorced. Some believe that the children of divorced parents become more likely to get a divorce themselves. Finally, the parents might hold off on a divorce in hopes that they can resolve their differences and become less incompatible.
there mums go sent to Johanna's berg to work there and the children stay with the elder does that answer your question?
Depends. Mine feels like one big adventure at the moment. Wake up at mums, go to school, travel to dads, stay at dads, travel back to mums, and then all over again! I'm sure it'll wear off, but my parents get on well, and I have a fantastic stepmum, so my experience is probably benificial. However, I'm sure people have their horror stories of parents threatening to kill each other, and going into houses with knives etc...

In one word, children. Women's desire to have children is an all consuming part of their life. Once they have children then their children become more important than career advancement. Of course children born out of wedlock and children from divorced parents tend to stay with the mother leaving her with even less time to focus on career advancement.
Because if they get married they should really stay together especially if they have kids that would be horrible for them.
Only if you are willing to live a lie and can be OK with that. Often, the children will be affected unconsciously by one or both parents staying together for the "sake of the children". Why would a person really want their parents to stay together despite no love or being unhappy?
