Who needs a piece of paper stating they are legally married? In our time, marriage, whatever its social, spiritual or symbolic appeal is in purely practical terms just not as necessary as it used to be. Many things contradict to marriage. Some reasons are having legal separation law. For instance, divorce and annulment of marriage. Because of this, long lasting relationship become elusive.
It seem that the vows no longer "till death do us part," but rather " for as long as i am getting something." It's like permissive liberalism has completely marred the concept of traditional marriage.
In my opinion why get married if you can break it. You can find people living together but not married are happy. Instead of marrying someone but your like a prison. So why do we need marriage, just to prove that you are legally married or to prove that you own this man/woman.
