Heartbroken after I dumped my boyfriend for paying for OF / camgirls

I left my boyfriend of 7 months when I walked upstairs to him asleep phone open to tipping OF and camgirls. He had mentioned he watched stuff before (like twice) in the 7 months we dated and I hated it but let it slide. I felt like this crossed such a line, especially since I fell asleep with him on the couch that night and we went ring shopping and he had bought us a house, and completely freaked out at him, and left him. There was lots of turmoil during the breakup and my reaction was exacerbated from during the relationship him always accusing me of looking at men when I wasn’t or policing who I follow on tiktok etc, slamming me in the door to go through my phone. I’m not proud of how I acted either when I found out, I called him creepy and pushed him away from me, but he never would even admit the camgirl stuff I had proof of, and I just am so sad 2 months out feeling like I lost my person over this and that maybe some people would have had a normal conversation about this and been calm and worked through it. We had issues in the past thought about him going through dms from before I knew him and stuff and putting me down / using it against me and I tried to be calm about that but it always came back. Any insight or similar situations help, I feel like I’m stuck in a horrible mental loop.
