According to The Wall Street Journal, Melinda Gates had been meeting with divorce lawyers since at least October 2019 after Bill’s business dealings with convicted sex offender Jeffrey Epstein became public, and she had warned him about associating with Epstein as early as 2013.
From her Wikipedia article:

You asked for context; not evidence.
You’re right, friend. Thanks for the context.
