>will in due time prepare a formal and in-depth apology where I plan to detail what exactly I am sorry for

Maybe actually leave her the fuck alone. Victims of sexual assault don't like to hear from the people who assault them. You'd only be apologizing to make yourself feel better. There's a reason why she doesn't want to hear your apology and that's because she doesn't want to have to make you feel better for being a predator. Leave her ALONE
