I asked because childhood sweethearts don't usually work out - people change too much in their 20s, I think. The exceptions tend to be strongly devout Christians. I'm not sure why, but perhaps it's the support from their church community? There's a certain amount of peer pressure, but also genuine cheerleading going on there. I was brought up Christian and I do think the community side of church-going can be a net positive for many people.
