would that work with the age difference? she'd have needed to be about 27 for him to have been 21. it works for me if you think she'd have been with women exclusively for that long! otherwise im cool with saying it was more recent. maybe it was an open arrangement and eventually they just decided to move on to different prospects? or it could have been when he was 21 but similarly an open arrangement that lasted for however long and ended because he didn't want to move in with her
