I remember in high school late 90s reading a short story probably in an anthology or collection about two lovers (man and woman), who time travel while they’re together in their apartment bedroom (possibly New York or a large undefined city).
The way I remember how they time travel is when they are in the bedroom together time outside goes quicker than inside (a few hours might be a day).
I remember as the story went on they stayed in their bedroom more often and only went out for shopping groceries so were spending less and less time in real world time.
They lost their jobs and might have invested in stocks or something to make money I can’t remember that part exactly.
It was probably written by an American author in an American short story collection. It was a simple well executed and romantic story about how time seems to go so fast when you’re together with a loved one. . It also had a great ending where they ceased to exist or something. As the landlord visited and the apartment was empty or something. That climactic ending gave you a nice chill wow feeling. I’d like to find it again because it is one of the stories I always remember but don’t know what it’s called.
