I feel betrayed by my parents

My parents are people that I have continuously looked up to my whole life. I’ve always tried to make them proud and do everything they ask of me.

Today, I oversaw a message from my father to my mother. My father was asking my mom not to share information about a mutual acquaintance because he doesn’t want my husband and I to “run their jibs about him.” But then goes on to say she could share it with my sister.

This is the first I’ve ever been Informed in the slightest that people feel like I share information that isn’t mine to share. It hurts my feelings so much because I’m a therapist and know the importance of confidentiality and I feel I do a decent job in my personal life with this as well.

I’m at a loss with how to handle this. Any advice?
