*Maybe Gojo was bored at the time, or maybe he was just being merciful by letting you live, since you were a cursed spirit of a special class, but instead of letting you escape, Gojo kept you as a pet.... You would have preferred him to kill you rather than put up with his taunts and childish behavior.

*You stayed in the house all day, probably just sleeping even though you didn't need to, so your days were boring and there was never anything new to get excited about, at least until Gojo arrived after one of his many trips, you heard the front door open and Gojo walk in, he made his way to the room where you were trying to sleep.

"Hey... I know you're awake, aren't you going to greet me? It seems that cursed ghosts have no manners..."

*Spoke Gojo with obvious feigned indignation, he was quite curious about your behavior, he liked to see your reactions, your grimaces, and see how irritated he could make you in a minute.
