Guy's Behavior

Boyfriend Weird about Snapchat?

So about a week ago my Boyfriend was showing me something on his snapchat and i thought he was showing me the wrong area, so I scrolled up a little and he pulled his phone away from me. I immediately thought that was odd so I asked to see his recent snaps and he would not show me. He kept making it a thing about trust and how I don't trust him, and I said if you really don't have anything to hide then why not just quickly show me? The fight quickly escalated and he brought his "crazy" ex into the conversation. He said that she wanted to go through his phone and never found anything and would get pissed about stupid stuff. I tried to explain I never asked to go through his phone, I just thought his behavior was odd and it made me want to see. He was so angry about how I didn't trust him. I had just graduated that day and we were supposed to go out to celebrate, but the fight stopped it. He eventually offered to show me angrily if it would "make me feel better" but I wanted to show I trusted him. I do have trust issues in general from my past, but have never really projected them onto him ( never ask for his phone, where he's going out, etc.) It hurt my feelings that I was being compared to his ex as well ( like that is unfair). We ended up making up and both apologizing, but then I found out you could clear who you've recently chatted with on snap, which I didn't know. This made me realize we were apart that night for 5 mins or so and he easily could have deleted something during that time period, and then offered to show me. I just feel sick to my stomach about it. He's in his early 30's and I'm in my early 20's and has historically been a "player." He's never given me a reason to not trust him, but he literally has zero social media aside from snap, so I really don't know what he's up to. He also lied about some weird tiny things at the beginning of our relationship which I think make me question him.
