Help!!

Okay so it's very possible I'm paranoid but 
I've been talking to this guy for about 3 months and really like him. He's usually either with me or with his friends but I'm back home for Christmas break right now. Last night we were barely talking and when he snapped me he never showed the other person he was with which he always does. I could've gotten over that but this morning he snapchatted me in what looks like a girls room. I'm not sure if it's within my boundaries to confront him about it or not. What do you guys think? What would you do?
