Bash away but it's just my personal choice & opinion. The father of my kids proposed ten years ago before we had children. I said, "i love you - but no. i will never marry." We are still together now and we have a happy family like any lawfully-binded couple. Obviously, I am not religious.
To me, marriage is an archaic institution and I understand it means a lot to many people but truly...walking down an aisle, making a few public promises (that are often broken) and filing joint taxes doesn't make anyone more of a loving or committed partner. For many marriage can even be a false sense of security. Men and women alike.
For those of you who love being married - I am happy for you. This is just my view.
