We often share our secrets or very private personal information with someone that we trust, like our best friends or people that we know very well.
Do we have a verb to say that we talk with someone, telling them all our secrets or deep private personal information?
For example, I chat with my best friend, or I confide in my best friend.
"Confide" works well only if you are speaking particularly of private information that one wouldn't tell nearly anyone. We nearly always "confide (something) in" our best friends, not "confide to": "I know that I can confide in you".
I think I nearly always resort to descriptions for this; I might write "We had a deep, personal conversation" or "I wish I had someone that I could really talk to about things dear to me.
One common adjective is "heart-to-heart", for example: "I tried to have a heart-to-heart conversation with my wife, but she was too tired to take me seriously." This usually connotes that there is a certain topic that needs to be discussed, unless it is used with more generalizing context clues, such as "I really like talking with Ann; our chats are always so heart-to-heart."
