So I am in a tricky spot with my single player world with a guild

So when the game came out we and my boyfriend started playing it very often. eventually (or originally) they added guilds and he invited me to one and such (idr the reason)

fast forward to know, and I'm still in the guild and I broke up with said boyfriend and we ended on awful terms. needless to say asking him to get on to make me guild leader is out of the question.

being in the guild causes no issue atm... I'm just wondering since the world has been and has only ever been on my console with only me ever playing it for 460+ in game days (I have daytime set to last for a while)

I want to leave the guild or own it myself. Yet when I go to leave it mentions losing the pal box and such. I don't want that... anything I can do? Or am I stuck being a member rather then the owner of my own world?
