The site she controls has not been updated since 2017.

It's no longer of value to anyone who may have been using it and becomes less valuable every day.

But you know that already.

It won't be long until no one goes there anymore, at all, so it's effectively dead and even getting control back at some point won't actually benefit you.

What you should do is register a new domain name that makes as much sense as it can and do an outreach campaign to known users to let them know about the change and rebuild.

Sounds painful but it'll be less work in the end than getting back something of no value.

Put another way, you are already at or close to the point where you'll need to do outreach and rebuild your visitor base anyway so why add dealing with her into the mix.
