Ugh, insecure..

Anytime my phone goes off my boyfriend wants to know who it is and what we're talking about, which I never really have an issue with. But when his goes off I simply ask if it was his or mine, hoping he might divulge who he's talking to at 5:30am, but no such luck. It makes me feel really insecure that he's got to know all the details but won't do that much for me. It kinda makes me wonder if he's so adamant to know because he's the one with something to hide. But logically, he has 100% no time to be hiding something, we work and live together - carpool even.
