would you be annoyed?

alright ladies so, i don't care that my man likes other girls photos, really, like whatever you want. butttt i think it's really annoying when there's this one particular girl who we follow mutually ( i can see his name under the likes) that he has "liked" every. single. one. of her photos. would you be mad? or is it just me? they graduated high school together and he slept with her sister but would drive this particular girl home from school and such (says nothing ever happened) but i still find it annoying... just me? and no i don't go through his phone because i trust him not to do something stupid i'm just annoyed and not sure if i should bring it up?
