Broken trust

What if you (40M) were visiting a close college friend (38F) with my wife (45F) and the friends husband (39M). And I shared something very particular, personal and private about health etc. leave the room and get random message from a former coworker who knows both of us asking me basically what I just shared in confidence with my friend (38F) who I haven’t talked or worked with for 8 months. You confront and friend and she swears she didn’t say anything
