How to stop my dad from seeing my Facebook activity?

[Brogan]

My dad only created a Facebook account (I did it for him) so he can look theough his news feed to see what I'm posting (when I made his account I sent a friend request to my account, without thinking). He now sees whatever I post, like, share, etc - and I 'like' a lot of posts and stuff, so I have to be careful of what I do. And whenever he goes on Facebook he mainly sees that I 'liked' something, so if that stopped he could get suspicious.
I honestly hate it, how can I get him to not see what I do without deleting him or blocking him?

It is possible to hide stuff from strangers (which you should always do), but you can't control human beings. If you like something, he either sees everything, or nothing
