I don’t agree [that marriage is necassary beacause we need to have order in society] because you can love and care for someone outside of marriage. You have to be able to, or there would be no marriage in the first place.
You can’t say that an unmarrriaed couple is unable to raise children as well as a married couple. What does a legal document and a religious ceremony prove anyway? Ridiculous!
I think that many marriages fail because there is a lack of understanding about what is needed to commit to another for the rest of your life. I don’t have the answers and I’m not pretending to, but getting married young is bound to be a part of this.
