How can I keep my news comments out of my FB friends' feeds?

FB’s new algorithm has made it so every time I comment on a news article, opinion piece, etc. it goes right into my friends’ news feeds and the same when my friends comment on things. Every single time I drop a comment somewhere, it’s the first thing my boyfriend sees in his feed.

I know that the internet is public and I don’t post personal info, but this is annoying to me and I don’t want to spam people’s newsfeeds and annoy them either.

Is there any way to fix this? I may just delete FB.
