Opinion?

I need your honest opinion about something personal that’s I’ve been dealing with. So my husband has a password on his phone he’s been cought watching porn in the past and won’t give me the password because he says he can’t trust me. That all I want to do is snoop. But I’m not the one that got cought watching it. He said hes stopped but in my opinion he’s still being secretive with his phone if it’s not porn it’s something else. He will be on his phone in the bathroom for long periods of time. I can walk naked across him and he doesn’t even notice me. It’s seriously affecting my self esteem. if he wasn’t hidding it then I don’t know what the issue is. Could he be talking to someone else? And he is aware of my feelings it’s been brought up but he just won’t budge to make me feel secure. Am I being over board controlling or am in my right. I know a lot of women are ok with there husbands watching porn and to each there own. But when porn gets in the way, and your husband becomes more and more distant and won’t even touch you. Sex is like not on the list with me. Then what else? They obvious is pretty obvious right? Or am I wrong? Can someone please help me out. Would this be a valid reason to leave the marriage. The fact that he won’t make me a priority or put my feelings first.
