IS MY BOYFRIEND HIDING SOMETHING?

This is soo has nothing to do with this app 😂 but I have a question for you ladies. If your boyfriend/husband doesn’t let you see their phone, are they being shady? My boyfriend tells me that he doesn’t have to prove anything to me, and that I should just trust him. And true, I should trust him, if he didn’t have a history of lying to me. So I told him in order to gain my trust back, let me see your phone whenever I ask. He says no, and that I should just trust him. Then he storms out the house, and blocks me.. and acts like I’m the one that’s crazy and that I’m the one that has the problem. I tried to explain to him that if he didn’t have a history of lying to me I would just trust him and I wouldn’t even ask for the phone. But since I have found messages between him and other girls, naked photos from girls, etc. I don’t trust him. He may not be doing anything, NOW but how do I know? That’s why if he wants me to trust him again, I should be able to see his phone whenever I ask. But he absolutely refuses. Can y’all give me ya’lls advice? Do y’all think that he’s hiding something?
