I'll just replace "girlfriend" with "wife" since I am married —
Nothing happens. My wife knows me well. There isn't anything I think would surprise her.
It is all automatic.
You maintain the same relationship after the move.
If you just followed them, but they didn't follow you — that continues after the move.
If they just followed you, but you didn't follow them — that continues after the move.
If you followed each other — that continues after the move.
It is all automatic.

As a user, if someone who follows you moves their account, you see that as a new follow in your notifications.
Yes — assuming it is safe — I have a family to support and care for (so have to think of them, too).
I want to see what's there — and see it first hand for myself.
Similar reason why I travel to different parts of the world to see things.
I think this is more than just curiosity.
That is what happens on Mastodon now when someone moves their account from one server to another — you get a notification of them following you from the other server.
It depends on what you mean by "replace".
The Fediverse may cause centralized social-media networks to join the Fediverse.
There are some hints of that happening now.
Facebook / Meta has created a new social-media network that is part of the Fediverse.
Tumblr and Flickr are said to be joining the Fediverse.
So, some "popular social media" may become one with the Fediverse.
Nothing is "official" on the Fediverse.
Because it is decentralized, no one controls it (and thus nothing can be "official").
I'm on the Fediverse, but not on Lemmy.
And I am replying to you.
Welcome to the Fediverse!
