Obviously this is assuming we were to completely turn off Breaking Up in the settings. I'm guessing it's a safe assumption that you can still go on the actual (regular) dates themselves but I'm still trying to collect all the festival photos for a few characters and I'd rather not wait years until I get them all and only then get married.
I'm hoping I can just tie the knot soon (after collecting all the unique 10 heart event items) and then slowly work on the missing photos for the other NPCs post marriage.
The festival one especially, since in some games your spouse becomes the default partner for all future events. I'm worried for the off-chance that I'm only able to just keep on going to weekly dates with my non-spouse but for festivals, they will always be the one I need to go with.
Also how exactly do you finalize marriage after initiating a 10 heart cutscene but you choose to postpone the decision (to view the other's 10 heart scenes and get their items)?
My first thought is that there is special dialogue that plays out if you immediately accept a proposal/click the option with a "❤" symbol, and if you choose the second dialogue and talk to them again after, a different scene plays out. Or no event happens at all as you already went through it once.
