My boyfriend tells all our problems to his parents?

Yesterday, I discovered that my boyfriend tells ALL of our problems to his dad.
No, seriously, all of them.
Obviously, I didn't like it, so he said that that is the kind od relationship he has with his dad, he gives him good advices when we have an argument through a text... he actually said his dad told him that " I probably have too much free time" (because we fight quite sometime) etc.
He even had to let them know that we had a pregnancy scare, and they even told him to buy a pregnancy test and called him to check results! He told his mum all of the pregnancy symptoms I had and talked to her about it, without asking me if I am comfortable to share such an intimate things with them!
I'm so ashamed really, I have no idea how to look those people in the eye. I told him that those are private things, arguments and sex, yet he doesn't listen, he runs to his daddy and mummy for advice for every single argument we have!
Worst, he just has a mentality "take it or leave it, that's how I am".
What should I do? I love him to death, but I don't want to live like this.
