Kinda of odd. Don't think I can help out with that.
The only thing I would suggest, from my games, is that Aria appears at Sewo Bend(?) beside Rambler's Cliff after you dismiss her from the action menu.
I had a similar issue with Caitlin when I first did her quests. She appears in Westside after you dismiss her.
Her affection and happiness just tanked. I finally noticed that I had left a large butt plug inserted for several weeks and that she was also naked the entire time (she doesn't like being naked for teaching and home schooling) and her Fear was way up because of the whippings and sexual demands. Ending up removing the butt plug, gave her clothes to wear stopped all demands etc.. and very, very slowly got her back to undying affection. Actually married after that as well.
