Her account does not describe “an existing sexual relationship,” but you start by contradicting that. (Not a good sign.)

(Instead she describes two meetings that left her uncomfortable; but says she’ll hold off descriptions beyond saying some of those details are worse. So start with examining what was behind your assumption, or your manipulation if that’s more accurate.)

But let’s imagine that your date was with a different person, one who had even carried a sign into the theater that said “We’re in an existing sexual relationship” so it was absolutely clear to you. And he or she then told you “not in public, not comfortable, that hurts, don’t want that, not interested, won’t be doing that, get off.” Does that different context help to explain anything?
