Friendships after marriage?

I’m (F) still in my early twenties but few of my female friends got married recently but we’re not so close so that’s fine but I was wondering how my current close friendships will change after they get married ? In my case, I still want to keep my close friendships the same..

So for people who have married friends, how did your friendship change from before to now, do you text the same or hangout the same or no? And do they share as much as before or now they keep secrets because family priorities?

And is it worse when they have kids? Or when you have kids?
