How long should I wait to try to contact a female friend who said she no longer feels safe/comfortable with me and never wants to talk to me again?

I don't wanna get into details, but we were very close friends for many years and never even had a single fight, and I thought our friendship was solidified, so I was completely shocked by this.

She seems convinced I had ill intentions and said she never wants to talk to me again.

She said she's one of those people where once you break her trust (or in my case if she thinks you did), it's over. But I know from experience that often people say things or act a certain way in the heat of the moment, but later have a change of heart.

How much time do you think should pass, before contact should be attempted again? People usually advise not to be too pushy, but also not to seem too desperate. I don't know if I wanna bank on her reaching out to me first. I'd really like to save this and the last thing I want is to make it worse.
