Well, there’s a big mistake right there.
Attachment and reinforcement of a love relationship requires continued recommitment to the relationship. I did read (and maybe even post) on the thread originally, but I can’t remember if someone brought up love languages. No, these aren’t based in logic. There’s nothing at all inherently logical in wearing rings, or buying cards/flowers/chocolates, or holding hands, or even saying the words “I love you.” In a vacuum, they’re all meaningless gestures. But in an attachment relationship, they can have great power.
Humans are symbolic creatures. We put meanings onto things. This has gone on for thousands and thousands of years. The cultural trend right now in the United States is, “married people - men and women - wear wedding rings.” There’s nothing at all essential about the rings or about who wears them, but the fact by itself that it’s the norm does give it some power. If you’re personally not into visible signs, you may think it’s silly or inconvenient, fine, and there’s examples of people who have made that work despite the symbolic norm today, or people from other cultures with different norms.
But I would be very cautious about dismissing people who value that norm. It can be taken to extremes, absolutely (especially the larger and more garish the rings get, though that’s mostly an engagement ring thing.) Really, though, I think it comes down to love languages. A ring is a visible symbol of love, it’s apparent to anyone who sees you wear it, and wearing it gives your spouse assurance that you will see it and think about her even when you’re apart. That desire for assurance is not silly at all.
