i agree with that, but it kind of also sounds like she's saying once you're in a relationship you have to bare all, and I feel like there's more nuance than that, tbh and if that's your expectation then no one will meet that because there will be times that for whatever reason shit doesn't get shared.
it also ignores the fact that i've known people who have happy committed relationships when they ignored the elephant in the room and didn't talk about something. I believe in being real to the people you're close to I'm only saying that its not 'not complicated'. maybe it is for some people and that's real but I don't think thats true for everyone
