Head Canon:
When Ren leaves to go on extended missions the General doesn’t handle it well.
He tries, the first week he manages to keep it together.
Week two, he’s working through his lunches and working later and later each night.
Week three it’s Wednesday and he hasn’t slept since the Saturday of the week before – he works all hours of the night just to keep himself busy.
When Ren returns from planet side, he finds Hux sleeping at his desk. He wakes him up gently and peels off his clothes. Every time Kylo peels back the layers he’s surprised at how small he looks with out all those layers on.
