what does marriage mean?

In lovers perspective marriage is bands which hold couple together and express their relationship to the society. Actually people marry because of many reasons such as religious, legal properties and social reasons. Probably they are not an obligation, they are necessity. It is appear to be case that unmarried societies led children to have many crimes or be abused many kind of problem such as fatherless children or one parent type of family. Maybe these are not seems to be a crime but I think that making a children without looking after them or without doing mother/ father function to the children is a big social problem. Growing without mother/ father love might be the most appear thing which hurt them in children life. On the other hand if couple is not married people are not responsible from each other, people can leave when they want to go or want to be together with other person. Probably this is the other psychological necessity of marriage. Briefly marriage is a necessity of human life.:)
