What should I do?

My boyfriend gets really mad at me over the stupidest stuff all the time. Today, I logged into his snapchat because he logged into mine and told him this girl snap chatted him (I don’t like the girl at all and he knows that because they flirt all the time) and he told me not to say anything back because he thought I would say something mean. Later, he was on facetime with me and told me I texted this guy a lot when I never do and then got mad at me because I wouldn’t tell him my eyes only password. I know this is really stupid and he gets mad at me all the time for the most stupid reasons and i’m starting to get really annoyed and tired of it, i’ve already confronted him and told him to stop getting so mad easily. What do I do?

**He looks at my snapchat all the time. I only get on his snapchat when he logs into my account to look at all my messages
