Update!! Is he hiding something?

I want your ladies opinion. Some background..  I've been with my boyfriend for 7 months. The first month we knew each other was rocky because I had been talking to another guy but I ended up telling that guy that I was no longer interested because I had met my now current boyfriend.. that guy respected that but my boyfriend rightfully so wasn't happy that I hid talking to this other guy the first month. But since then I have not talked to other guys and I don't care to at all, I'm truly sooo happy with my boyfriend and to ease his mind I allowed him to go through my phone whenever he wanted and also gave him my passwords. I had nothing to hide and I really did want to make it work and I voluntarily did that to make him feel comfortable in the relationship so he didn't think I ever was hiding anything else. So here's where it gets confusing, he has full access to everything of mine but he has been sooo weird about me going through his phone. I never have been given the chance to and I don't know his code to even sneak it. Many times I have asked to see his phone, I'm curious because he can go in mine but won't ever let me in his, so it gives me paranoid doubts. But when I ask he'll say yeah hold on, and then quick change his mind one minute later saying no I'm on it or I'm using gps right now. Well over the weekend we were drinking and I asked to go through his phone.. he said yes I'm using gps, let me get on the road I know and then you can see it. Well he gets on the road he's familiar with turns off his gps and I ask if I can see it and so of course he refused and said he needed the gps again. We fought and then He said it was because he has his banking stuff on there and that a girl had previously stole money from him, but I kinda feel like that's bullshit. 1. Because he could watch me go through it so he could see I'm not on his banking stuff and 2. I would never steal from him let alone ever gave him a reason to think that. We got in a huge fight about it and the alcohol didn't help. It just didn't make sense to me why he's so weird about it. We ended up making up and the next morning I brought it up again and he said his usernames and passwords for everything out loud. Well it only worked for his instagram. Well when I got on his instagram I went to his blocked users and I noticed a girl that constantly likes his pictures was blocked. It has me thinking he blocked her because maybe he didn't want her messaging him when I was snoooping? Idk if there was a past between them. I just don't understand why this girl who has always liked his pictures was all of a sudden blocked when he gave me passwords. This just makes my suspicions worse. Am I being crazy? I have never felt paranoid and wanted to go through my boyfriends phones ever, I respect their privacy and also trusted them but since he's refuses to let me go through his phone I constantly just want to get on it and see if he's really doing anything.
