Really need opinions

Hey everyone, so I’ve been in a relationship for a year and a half now and we live together. As we were going to sleep last night he asked me to charge his phone and as I’m doing so a notification comes in from Snapchat from a girl that he messaged letting her know she posted a really cute picture and she replied to him. I got upset at him and asked him to leave me be for the night and why he was doing that. He said it’s nothing bad there’s nothing wrong with it. I let him know, okay fine there’s nothing wrong with it. But when I see a guy that posts a really nice picture I’ll be sure to let him know it’s a really nice picture and he got really upset saying to not start with my bullshit. We argued about it for a few minutes and I turned and asked him not to touch me and fell asleep. I woke up, still annoyed by the fact that he thinks it’s okay on his end and not mine and still asked him to leave me be as he was trying to be all cuddly (he is only cuddly when he’s trying to get me un-mad) and he stormed off slamming the door saying it’s bullshit and he didn’t do anything.

I’m not mad at the comment he made towards the girls picture, I am not the jealous kind in that way. What upset me was the fact that he thinks it’s okay for him to do this, but if I were to do it he would most likely say we’re breaking up.

Am I wrong for what I did?? Like seriously I don’t understand his mindset??? #INEEDOPINIONS
