I disagree with this. There are boundaries in a relationship e.g. I don’t read my wife’s email even though her account is on all our devices. But it’s a social contract between people not an absolute standard. And if a partner in a relationship is breaking that social contract, then the boundaries shift. Should a hookup be going through your phone? Absolutely not. Should a long-term partner do it if you start acting strangely? Maybe.

In the context provided, the action was beyond the social contract OP committed to.
I’m not so sure, but I guess that’s at least part of the discussion.
