When she first said no, and he persisted, and then she acceded, she trained him into believing that persistence pays off. So when she says no again, it seems to me that it is almost mathematically predictable that he will re-double his persistent efforts to win her back.
'no means no' does not apply when it sometimes means yes. With added flakiness, 'no means no' means : 'no means yes once in a while, and no means no when I feel like it, and you're a rapist and I'm still an angel if you cannot figure it out'.
No.
Which means, no.
