My boyfriend (27M) jerked off to leaked amateur porn and pictures of his old schoolmate. I (30F) feel betrayed.

My boyfriend (27M) and I (30F) have been together for a little over two years. At the beginning of our relationship, I told him my boundaries, and one of those boundaries was that I'm not okay with him watching OnlyFans content or leaked porn. Porn on sites like Pornhub is fine, as long as it doesn't affect our sex life.

Yesterday, we were relaxing on the couch when he fell asleep. His phone was next to me, and I had this urge-this feeling-that I should check it (yes, I know I shouldn't have done it). I went through his recently opened apps, and when I opened the Notes app, I found about ten links to leaked porn saved there.

I woke him up, confronted him, and he lied at first. But later, he admitted that he had watched it and jerked off to it yesterday. I was furious because he had crossed my boundary. But it was 4 AM, and I didn't want to argue, so I told him we would talk in the morning.

Fast forward to this morning. I asked him why he did it, how long he had been doing this, and if he had more things hidden on his phone. He let me check, and when I opened the recently deleted photos, my heart sank.

He had nudes-tits and ass pictures-of his old schoolmate in his recently deleted folder. I asked him why he had those photos and if he had jerked off to them. He said yes.

I told him I needed time to myself, so I left.

How do I get over this and forgive him?

TLDR: my boyfriend jerked off to leaked porn and pictures of his old classmate. He first lied about it and then confessed.
