Let's talk some marriage, shall we? My opinion on marriage as something that isn't for everyone still stands, but let's back up. The reasoning behind marriage has varied a lot throughout history: trading daughters for profit, marrying off daughters to build social standing, religious reasons, love, contractual arrangements. Even today there are many different reasons.
If we're completely honest, marriage is nothing more than a legal document. Because of that, marriage in the sense that we have come to know it needs to be recognized as a legal step more than anything else. In today's world, couples can live together as a cohesive family unit without the paperwork so it really isn't necessary to take that legal step unless it is something that you are wanting.
As I keep reiterating, we're all different. Legal marriage was one of those things that I always wanted out of life, but really it is just some paperwork and benefits you don't have to have. Maybe for you and your relationship, paperwork isn't what fits best. But maybe a legal union is all you want without some of the other aspects (spiritual, physical, etc.). Moral of this story, know what exactly it is that you're wanting and why so you can make an informed decision.
What is your opinion on getting the marriage license and whole shebang as opposed to someone with a common-law marriage? Or maybe just shacking up or someone married to disguise their sexuality?
