Technically, the romance can still survive even if you slept with Aerie in SoA as long as you play your cards right. I know this from experience...

...The first time I beat this game, I was about 13 years old and I must have thought Aerie was the cutest or something (way different opinion than now, but I'll leave it at that). Aerie had the "show you my body" conversation with me in my Thieves stronghold in the docks during Chapter 3, and I (being 13 years old) accepted her offer only to find out that she felt used in the morning.

From that point on I noticed no real change in her demeanor despite reading many pages on the intarwebz. Events still happened as if she was an active romance, and a certain scene near the end of SoA gave me the option "Aerie, I..."...which is generally reserved for romantic partners.

And then everything unfolded as it should in ToB. I don't know why the romance didn't end after I slept with her. I had no mods installed, and I never used the console or Shadowkeeper.

Perhaps it survived because of the battle I went through with Haer'Dalis to win her heart. I played it perfectly and HD gracefully bowed out and offered to sing at our wedding. I don't know. My long-winded point is that sleeping with her may not always break the romance.

Sorry for this rant, but I'm bored right now.
