No - we live in ‘modern times’, as you say, so the idea of an engagement being for the woman is actually very retrograde.
When you say ‘for better or worse’ about modern times, do you feel that some of the expectations some younger people have been conditioned to have about documenting and/or sharing intimate moments like this are unrealistic? If so then I would agree with you.
I genuinely don’t understand how your fiancé could make sure that ‘the moment’ would be captured unless a photographer was hired. If that’s what you were expecting then I don’t really know what to say except that life isn’t a performance or a film. Social media and celebrity culture have really warped ideas of what’s normal.
If the point really is that he didn’t listen to what matters to you and this really matters to you then maybe he isn’t right for you. If he doesn’t share these values though, then to be honest you might have actually got lucky and be better off staying with him than finding someone who prioritises more shallow things.
You’ve also said he knows that he’s punching though - how awful for him not to be on an equal footing and equally valued within a relationship. If this is real, which I suspect it isn’t as it’s so silly, it might be a kindness to let him go so that he can find someone who values him.
By the way, I say this as a definitely-not-old person who herself lives and got married in ‘modern times’. All times are modern when you’re living in them, by the way, unless anyone has invented a time machine that I’m not aware of?
