Ok hear me out my boyfriend for some reason has hidden certain people on his Facebook list? not sure why? some old friends? ?

he hasn't done it with any of his new friends far as I know.

ok, basically I noticed he is following or friends with a few people now. that are not on his friend list I checked to see their friends list and it wasn't showing either yet seen it in his feed. also, the person's profile has no opinion to add as a friend or follow. Should I be worried about this? why would he hide them from me? they only talking about cricket. from what i saw on his feed while he was reading. can the other person have done it? with his friends. as he doesn't show up in his ether.
