Betrayal and my secret revealed

I had this very very important secret of my life and only couple people in my family and my future husband knew about it. Unfortunately my bf told everyone (almost all his friends), kind of unintentionally, but anyways. It made me extremely sad as he knew how important it is, and now he's apologizing all day all night. I don't know what to do, he betrayed my trust completely. It was pretty unintentional but still! What would you do? 😔
