This, all marriages are supposed to be this, us vs the world, while I get the argument you don’t know who you really want when you are 20, I’ve also seen cases like yours, as long as both people figure out us vs the world, I think the marriage will last. So when people say 25 and after it makes sense, I’ve also seen cases where people never understand in their life this us vs them mentality, and are never happy and I always wonder the question how much age plays a role in people understand what marriage is supposed to be?
Anyway thanks for your take my man, my condolences, I wish you all the best.
