Our old guild chat is nearly empty. Should I stop trying to bring everyone back?

I posted a Saturday sign-up and got two thumbs-up reactions but no names. An hour later, four former regulars were playing another game together in a different channel.

Nobody has fallen out. Our campaign ended three months ago, and people moved on. I kept the old guild chat active with screenshots, polls and suggested runs because that was where we used to meet almost every night. A friend told me, gently, "You can come with us. It doesn't have to be through the guild."

I know that. But joining their new group feels like leaving the one I spent two years organizing. If I stop posting, the old chat may become an archive rather than a place anybody visits.

How do I let the guild end without turning it into an accusation that the others abandoned me? I want to preserve what we did together and still be someone they invite to the next game.
