Why can't she say she was drunk, going to his apartment seemed like a good idea and they became intimate until she had second thoughts?
The story has too many holes in its timeline for this not to be a plausible explanation. You can create worse scenarios from the same facts, but it seems questionable that Richmond carried her passed out to through the streets of Florence to his hotel. She most likely agreed to it and was self-ambulatory even if she was intoxicated.
The sexual contact was probably ill desired, but it sounds like it stopped when she wanted to stop and again, we have no good explanation what put her on the bed in that situation to believe in unless you're subscribed to the idea he brought her home in a passed out state and put her on her bed.
The worst you could say that Richmond was opportunistic and a cad.
My belief is you can't call buyer's remorse sexual assault and you don't get a pass for getting intoxicated and making bad decisions that result in unwanted circumstances. It doesn't justify forcible assault, but it doesn't condemn sexual advances when you've willingly gotten into bed with them or agreeing to have sex for that matter.
Too many women are making bad decisions and having cognitive dissonance about it afterward and then seeking absolution through blame because they can't live with their mistakes.
