Why do families breakup?

Families break up because of many causes. Sometimes these issues are made into huge public affairs whereas others are kept within the family. These issues could be because either one of the parents loves somebody else, they never agree to anything and they think that they won't be able to make it work, either parent is extremely low on patience and the other is low on tolerance- why there are so many reasons. Sometimes you don't even know the person that you are marrying and therefore break up with them because you don'tlove or even remotely like them. These are some of the reasons that parents break up and leave your family broken for a while or forever. If the breakup happens with another member of the family it could be because that person has done something very wrong, they have had some falling out, or just the reason that the person wanted to do something they loved and therefore left so that they could pursue their choice of a career. Daughters could even run away and feel too ashamed to return to their families.
