I feel my boyfriend is taking me for a fool what should I do? Please help?

Me and my bf are together a year and living together for 2 weeks, he got a new I phone a few weeks ago but has recently put a code on it and brings it literally everywhere with him. I asked him why he had a code on and he said because he wanted to and when I said he was hypocritical for accusing me of hiding something before he said I was an idiot and then just brushed it off like nothing happened. I feel like hes takin me for a fool. What should I do?
