If someone REALLY thinks that there can only be extremes (e.g. "I tell them EVERYTHING" or "I tell them NOTHING!") in a relationship then you most likely will fail in those.
Relationships, just like any other interactions with other human beings, is about weighing up whether or not something is important enough to even bring up.

Does it REALLY matter that I claim "Nah don't worry, that cake I bought you was only 1 Dollar" even though it was 5, but I wanted to treat my partner to something? Remember, you claimed sharing ALL is important.
Does it REALLY benefit your relationship, telling them that you really hate their guts, even though 1-2 days later it turns out this hate was completely unwarranted, because now you have a full picture? Remember, sharing all. And not sharing is no true love.

Only dealing in extremes is not good.
White lies are a healthy.
Practicing restrain to give yourself and your mind room to think is good.
Relationships are no anime.
