unbosom (oneself) to (someone)
To share one's deepest or most intimate emotions, thoughts, or secrets with someone else, especially in a profuse or sudden manner. I had simply asked him how things had been, when suddenly he unbosomed himself to me about all the problems he and his wife had been experiencing lately. I apologize for unbosoming myself to you like that. I'd been holding on to that secret for a long time and just had to tell someone. I hadn't expected her to unbosom herself to me with a confession of love, but it made my heart soar to hear it.
