Slip

Mae works at an art museum and has been living with Elijah for thirteen years. While there is still love between them, there is little romance to be found, and they have hit a standstill around Elijah wanting a child and Mae feeling apprehensive. When Mae "slips" and has a one night stand with Eric, she wakes up the next morning in a panic, only to realize she has somehow entered a parallel universe in which she and Eric are now married, and all traces of her life with Elijah have been wiped from existence.
