Boyfriend telling on me 😅

My boyfriend talks to my mom and/or dad after arguements we have and ask them for advice and sometimes tells my mom and dad if I say things that are "mean." I'm 17 and he's 20. He said that he tells them because he's never had a mom to talk to about things because he's grew up in foster care. I told him how much it bothers me and he still continues to do it. What should I do and how do you feel about it?
