I'm the DM for a Homebrew campaign that I've been running for about 2 years. Our group is me plus four players and we've been lucky enough to meet fairly consistently on a weekly basis, so I'm loathe to be asking this question at all.
The situation
We meet at an apartment shared by two of my players (let's call them Jack and Jill), who were dating when we started the game. They broke up about a month ago but we were still playing up until now. However, today Jack messaged me saying he's no longer on speaking terms with Jill and never will be again. He is looking to move out as soon as their lease ends.
Obviously this creates a difficult and awkward atmosphere for all involved, and playing with both of them will be impossible. But I really don't want to have to scrap my game entirely. I also don't want to seem like I'm "taking sides" (even though I don't even know what happened). Our party has generally all been good friends outside the game up to now, as well. We frequently hang out together for board game and movie nights outside of the campaign.
I do not want to scrap my game, but I also don't want to cut ties with my friends Jack and Jill. What can I do to salvage my game at this point? Should I jump ship and get two new players entirely, or pick just one player to "keep"?
