Marriage is just a symbolic piece of paper. It doesn't change the way I felt about Sharn. I know that might be a shallow approach, but it was a party, a ceremony, some government paperwork, and ... nothing else really changed except "my wife", "my husband", and her last name.
Love, to me, exists outside of labels like marriage and all that sort of stuff. It doesn't increase loyalty, or anything beyond that.
In fact, I wanted to vehemently not get married, because for the most part, marriage is seen to be a religious custom, and if I do not put myself into that category, then I betray my beliefs (I couldn't think of another word!) about it. As a governmental / administrative things, it didn't make life any harder or easier.
I dunno, I'm rambling incomprehensibly, constantly trying to contend with the fact that some day, all things will end. I do take the "til death do you part" bit of the traditional vows very seriously.
