She left him over trust issues and it’s implied he didn’t have a good alibi for Epstein. We don’t know if Bill actually did anything, but Melinda clearly didn’t trust him in the end. Bill also came across as controlling (not surprising) and she had to just suffer with the lifestyle he chose even when she disagreed.

She clearly cared more about philanthropy for the sake of it than he did. She also was more interested in being modest despite wealth. At least modest for being that rich, I don’t actually know how modest she was/is but she wasn’t into big mega mansions.

For a lot of us we can’t simply leave. And if we can, it could still take years for visas. If we are lucky it will be short, but I’m not too optimistic.
