Thanks for that. Very interesting and indeed a good thing.
A marriage has everything to do with romance in terms of the kind of relationship we're talking about: a romantic relationship.
Personally, I haven't made my perspective clear in my original comment. Me and my partner have lived together for some time, we have kids and our own home. I definitely don't expect a bed of roses after marriage. In fact, after the experience, it would be pretty damn foolish to expect that from a day to remember, a legal document, a few things and nice holiday.
Despite that, I still fail to see how I, myself, could serve my partner with a pre-nup after knowing, by this time, she is the person I want to spend the rest of my life with.
My opinion is perhaps related to your first paragraph in that I have 0 pressure to get married and I have hafthe luxury of giving myself the best part of a decade to make that decision. That is why in my case I wouldn't serve a pre-nup - it would pretty much say "hey were getting married after a decade of commitment and realisation we want to spend our lives together but I still don't fully believe we will so best sign this just in case". That doesn't really show commitment to me.
To conclude, I would absolutely get a pre nup if the relationship was quite new but then again I wouldn't get married like that so hastily.
To me, marriage is the highest honour you can bestow on someone. You are in effect both saying "yes I honour this person so damn much, I want us to join families". That's a major thing and it actually kinda hurts to see some people treat marriage in a way that decreases its great significance.
