Is it normal if i want to keep my relationship away from family and friends?

Is it normal or okay if I want to keep my bf and relationship away from my family and friends? I want to do that basically just to protect us cause people judge, people are snooty even when they act all innocent, people think they know but they have know idea, people analyze and tear things down to make themselves feel better, etc. You know they say the couples that don't put themselves too out there especially in social media are the happiest which I can believe. We are happy together when its just me and him, then we come around "friends" or just pple in general and I know they are observing or at least trying to see whats going on between me and him. When we would hang out with them a lot, it was very iffy between me and him but every time it would just be me and him, things would be cool. Even worse with family. I do not want my family to be too comfortable with my bf and our relationship because then things get messy. I think it's better if we all don't get too involved with each other. Like I said going back, people judge real quick and it's pretty shocking to see what pple come up with when they just jump to conclusions. So i dont want anything to ruin my relationship. If we have problems, its between me and him. I hope its possible to keep them separated but I just wonder if its normal, if it is then I know we can do this forever. If its not, then that means eventually we'll all have to get involved somehow and that sucks.
