My girlfriend of almost a year went thru my phone and found something traumatizing

So me(M27) and Jocy(F27) got really serious in a relationship and we started living together. We did everything together we had an amazing relationship. Until she got insecure and started going thru my entire phone often.

Well one night after we had a beautiful weekend full of love making and dates and lots of excitement she decided to go thru my google photos. I thought I had deleted every single photo and video of my old ex from a year ago. But Jocy went into my old emails on Google photos and went all the way back to 2019-2021 and found videos of me having sex with my ex. She immediately left for work before I woke up, she dumped me when she got to work. I went to work and I tried calling her brother to see if he could talk to her so we could try and fix it and she got so triggered and upset that she packed all my shit and took it to my moms house. I cried at work. Our lives were just about to get to the best part and she destroyed us. I reached out to her closest friends and they all turned on me and talked shit about me and they've all convinced her that leaving me is what's best and she said she'll never forgive me and she never wants to see or hear from me again no matter how much I grow. I really love this girl and if the shoe was on the other foot I would have forgave her. I really didnt know about what was in my other emails on my Google photos. Everything has since been deleted. I miss her like crazy and Ive never had someone love me so much while we were together. Shes turned cold hearted and talks to me so mean now. I just cant believe how fast this all happened. I love her to death I wish she'd come back thats all I want. What can I do for her to love me again and forgive me so we could start a new relationship. Im destroyed. I traumatized a really good girl. I want her back. Help
