The last wedding I attended in the US was probably six years ago. Full Catholic mass inside a church, which I endured for the sake of the friend who was getting married.
Husband grew up in Europe and his family is still there. We got married at home in California, and it was his family's first visit here and probably the only such long-distance international trip his parents will ever take. We saw the interesting places separately after the wedding.
Of his siblings who are married, one was at a beautiful, old city hall. One was outdoors. I didn't attend (mainly due to timing and distance) when SIL married her wife, but safe to say it was a secular venue and service. That leaves two siblings-in-law who are committed but not married, if having houses and children counts as committed.
In California, I know a very-openly gay man who is happily married to his husband for about as long as the law here has accommodated that. I don't know them well enough to have been invited, but the man has since become a pastor.
I've concluded that there's not much correlation between the wedding and the resulting marriage, other than that sometimes, weddings bring out strongly differing opinions about what constitutes the "right way," which can portend ongoing strife and bitterness. I know one friend who, I suspect, divorced her mother-in-law as much as her husband. From what I knew of the wedding preparation, that dynamic was there from the very beginning. I suspect a heavy dose of tradition, if not religion per se, was partly to blame for her MIL's unbearable overreach.
