AITA for now reacting to how he reacted to 'bumble' photos popping up on his phone after how he reacted?

I've been seeing this guy for about 5 years and he's not perfect and neither am I. He 'M37' and 'F28' I was using his phone (which he gave me) to show him a new trailer and how it looked awful, As I exited the app, "Bumble" briefly popped up—at the time, I assumed it was an ad and moved on. Idk if it was the app or he had screenshotted a conversation or a girl on their. Suddenly, he snatched his phone away and started accusing me of snooping, saying he "made sure nothing was open like that."

I hadn't even reacted or thought much of it, but his defensiveness made me suspicious. Now I feel like he exposed himself, and instead of addressing it, he’s deflecting, accusing me of invading his privacy when I didn't do anything like that. Nor would I, because I honestly had no reason to. I can’t even talk to him now because he says he’s "too mad" and says I'm just like other girls he's had in his life that snoop and don't give him privacy.

I don’t know how to react from here. I feel like any reaction will just "prove" his false accusation, but I also don’t want to ignore what’s probably happening. Over the last few years I got chronically ill, so I can't help but blame myself because I'm sure I don't look nearly as attractive as I was when we met. And I know I ruined his life by meeting him because he always says that when he's mad and he's right... Honestly I don't know how to feel. A year or two ago I would've been mad because I had a miscarriage with his kid and that's another story and not why he says I ruined his life but never less it was for the best because at that time he didn't want me in his life and wanted another girl, his ex. And then that's when my health issues began and then I got COVID and it went down hill after I got seriously sick and didn't recover after that and developed some permanent illnesses.

I just feel numb, like I don't know. I don't know how to react or what to think. I took our 5 years together as a serious, as it was my first major relationship. But I'm clearly blind because he doesn't see it as anything, especially after his reaction. Im a mess now and all I can think of is he clearly doesn't care about me anymore. Probably never did and was just lonely and I was all he had at the time. I had probably never experienced love before him, that I had towards him. I loved him deeply and now I think he never has and was just waiting for another person this whole time. I'm just heartbroken and he'll never understand that. Or how it makes me feel or how I gave myself to him. It's stupid. I'm a grown ass adult. I shouldn't be this beside myself right now.
