social media ruining my relationship

Ni
Ok so besides this and snap chat I don't really do the whole social media thing. Even my snap chat account is super private and only good friends are on it. I'm used to dating older me who really only use social media for family and friends or work. I have been dating my bf of two years and I moved in with him about 4 months ago. I am now starting to see how addicted he is to social media. I'm not jealous or feel like he's talking to girls or anything like that. It's just annoying like he wakes up and watches videos for hrs. He's ask me advice on what pictures he should post like I feel like that's a girl thing. Idk maybe I'm tripping but it's a major turn off. Like why do you care?! Wishing he would grow up a little. Things were perfect but I dnt think I can date an immature social media crazed man child. Also when I talk to him about it he thinks I'm only upset because it's easy access to cheating which it is, but I'm not worried about that part as of yet. He gives me no reason to doubt. However I never been naive so we'll see.
