relationship advice?

me and my boyfriend have been dating for a month now but i honestly dont know whats going on sometimes he goes a whole day without talkin to me and then he comes back like nothings happened , he doesnt want to put our relationship out there like on facebook or snapchat he always has stupid excuses, he gets messages when im with him but i never see them cus he doesnt show me , he doesnt have to but i feel disrespected cause i dont know whats going on there was a time a girl told him she misses him and he quickly took the phone from my hands ...we were watching youtube videos. but yeah we hang out like once or twice a week and then on the weeknds he kinds of dissappears and i feel like if he doesnt want to talk to me sometimes because he leaves me on read and im always the one double messaging him even after ive been left on read.
