[Neo Genesis Evangelion] What happened to Shinji and Asuka after the Third Impact?

I know Shinji and Asuka were the two people left after the whole Third Impact, but I wanna what exactly happened. Were they just left there? I am also not sure if Asuka died or not after Shinji decided to kinda, choke her for some reason, and they show presented showed her as still alive, I think? I am not sure, I know about the rebuild series and the time loop thing though, but I am not sure if the time loop happened immediately after or after a long time after. Is there even a specific time loop that occurred after the first? I am trying to figure this out still and it's a little confusing, so an explanation would help. 

(I put this as a spoiler because since Netflix put the show up on their website and now people are watching it. People might get into the series and other stuff that way so yeah, I don't wanna spoil it for newcomers.)

They were the first two, they might not be the only two. Anyone who can self-actualizes and choose to live despite the possibility of pain could come back if they want to.

Now they have to learn how to live with each other, knowing that they can hurt or comfort each other.

The time loop thing is a theory, not yet explicitly confirmed.

The manga shows a somewhat different end result, which ends up with the world mostly having been recreated as it was before the Angels, except that Gendo and Rei are still gone, and shows Shinji and Asuka meeting again for the first time with no memory of each other.
