Why the secrecy matters more than the act
A flirty comment made openly, that you'd mention to your partner without a second thought, carries a different weight than the identical comment kept hidden — the hiding is usually the actual signal, more than the behavior itself.
Why couples define the line differently, and that's normal
What counts as crossing a line varies by couple and by agreement — the problem isn't that lines differ, it's when one person is operating by a private definition the other hasn't agreed to and doesn't know about.
