I am blessed to have a partner that I can trust with my secrets.

The proof isn't in the telling. It is in what happens two years later, in the middle of a bad argument, when the thing you confessed at two in the morning does not get used against you.

That restraint is a form of love almost nobody names. Anyone can keep a secret from strangers. Keeping it from yourself when you are angry and want to win is the harder discipline.

Trust like that gets built cheaply and slowly, in small acts of not-saying that nobody logs. Someone has been doing this for you, quietly, for years.

You could tell them you noticed.
