I need opinions

I need on advice on an I tripping or not.. so I talk to this guy.. long story short his daughters 8th grade grad was last week. Pics was taken.. not family pics but mom, daughter and friend and then dad and daughter. Pics was posted I wasn't upset bc it's a special occasion and they looked casual fast forward until today I go on fb and he posted basically a repost of the pic of the mom daughter and mom friend.. I'm really feeling something type of way about it. Am I tripping or should I address this? I don't even want to talk to him .. he's probably so clueless but it's not ok and I feel a way, am I tripping or how should I handle this?
