his secretiveness is driving me nuts!?

my husband is very secretive w his phone, email, YOUTUBE, and bank. he wasnt like this before, until after our separation 2yrs ago. hed be sitting on the couch and whenever i have to walk behind him, hed cover his phone w his hands. and when i go over to him, hed flip his phone over quickly. not that i want to see what hes doing, he just does it. but sometimes he doesnt do it. howver, when it comes to me touching my phone, he always, ALWAYS ask what im doing, come over to look at what im doing, and judge what i do on the phone. like if im playing games, i like cooking games. hed criticize me and say i dont even know how to cook professionably, so why am i even playing those games. even the movies i watch, hed yell that why wont i find something to make me smarter. and when i listen to a guy singing on youtube, hed be jealous and act like why dont i find something to learn. ive talked to him about his secretive behavior, and he said its because he doesnt trust me and i make a big deal of everything he does, like seriously!? YOU MEAN YOU!? i only make a big deal when he watches porn and go to adult sites. i really have the urge to snoop into his damn fingerprinted phone
