How is this fair?

A while back I noticed a girl on my boyfriend's Snapchat. I calmly asked him about her and he tells me they just talk sometimes, nothing to worry about. I believed him. He's never given me a reason not to trust him. But when the tables are turned, and he sees a message from a guy on my phone, he FLIPPED OUT! Didn't even ask me about it, wouldn't hear what I had to say. I thought he knew I would never cheat on him. And I haven't! I've always been understanding, why can't he? It's been 5 days since this "overreaction" and he still won't talk to me. 😟
