I'm not single but, in terms of the topic (of making a wife/husband and of the marriage ceremony part)...
This is something I've been thinking about with my second wife.
She's South Korean, and thankfully has been raised in that much more traditional culture than most American women. Many of the ideas of submission and following and so on just come naturally to her, and I've had to 'train' her very little to those general concepts...instead the teaching has been about ME, and MY household (and poly life in general), rather than 'wifely' stuff. So, that has been a blessing. But my point is that it will be easier or harder for some (men and women) to become the spouse they are meant to be, but I think that is based not just off personality but largely culture. Find someone who HASNT been poluted and brainwashed by our western culture and you'll have a much easier time of it.
As to the marriage ceremony, same thing sadly is true there as here. She and I are married in the God sense of the term, but she still misses the cultural construct of a big wedding ceremony. For her it isn't the ceremony that is important but the party, the community. Personally I've never been one for 'groups', and my general distaste for the American church makes the idea make my skin crawl. But I also see the value in 'proclaiming' ourselves to the world, and publically hearing support from those who support us (so that the world doesn't just see our committment, but sees our circle's committment to protect and encourage us). Right now she is finishing residency at a Christian program that would likely kick her out if we 'went public', so we are waiting until she has finished to do any public ceremonies. But what will it look like? I'm not sure. A part of me wants to make her girlish dreams come true and give her a big wedding with all her family and friends and a big party, and only skip out on the 'officiated by a pastor' and traditional vows part. I'd do the vows ourselves instead and sort of 'MC' the thing ourselves. But the other part of me worries that doing the big party will only encourage people to judge us and discourage her from marrying into a poly family MORE, rather than being encouraging. Hmmm...
