One of the really silly features of modern life is the amount of energy and time that people put into weddings. Far too many people claim they simply can't afford to get married, when in fact it would only cost them a couple hundred bucks maximum to pop down to the registry office and fill out the paperwork.
Indeed, marriage is one of the most democratic institutions in existence, genuinely open to people of any means whether great or small. What they really mean, of course, is they can't afford an incredibly flashy and expensive wedding.
Those who enjoy loving and successful marriages know that the wedding isn't the marriage; it's not about the dress or the cake or the gifts. That said, how you do the wedding does matter. It's not the only thing that matters, but it is a chance to state to your community that you want their support in building your new family.
If you are from two different backgrounds, it's a chance to state how you intend to blend them together. It's a chance to welcome people into your lives who might have been absent for some time. This goes double if you have a big family (whether genetic or chosen). It goes a hundred times over if you're staging a public wedding and marrying a prince. So, let's see what statements your wedding will make, and that might shine some light on your ideal relationship!
