Should family be in your business

Mh boyfriend never wants me to talk about our buisness in front of his family he wont take a call about or buisness or even text me if they around because he doesnt want them in our buisness when we have issues so i have to be on hush mode wen they ask how we are, do you really have to keep your buisness to yourself? I would love to have someone to talk to like his mom or dad about what goes on
