AIO: My 27F potential boyfriend that I've 23F been dating for two months (not official) went through my phone.....

Okay, so where do I begin? I (23F) have been seeing this guy (27M) for about two months now. We went out on Valentine's Day, and since then, we've been inseparable. He's doing extremely well financially and he’s taken great care of me since we met.

During the first month, he insinuated that I didn’t actually like him as a person and that I only liked the things he does for me. I’ve tried to reassure him—many times—that I really do like him. The problem is, I’m just not a hypersexual person. Yes, we do have sex and do all the "relationship" things, but the issue is He feels like, because of everything he does and buys for me, it should be more consistent.

After a few conversations, where he was upset with me, I tried to be more romantic toward him and make him feel more wanted. I thought things were going well, up until yesterday. During my lunch break, I decided to hang out with him, and I ended up falling asleep. While I was asleep, he went through my phone. I didn’t realize it at first, but I could feel the shift in his energy. Later that night, he told me that he found messages between me and one of my old guy friends.

I was telling him a story one day, and this friend was involved in the story, but I didn’t mention that I’d slept with him a few times in 2022-2023. I understand now that I should’ve been upfront about it, but at the time, I didn’t think it was necessary. We were still getting to know each other, and I didn’t feel like talking about my past sex life so early on.

So, he read all the texts between me and this guy dating back to 2021, and he was extremely upset. He says the way I interacted with this guy, and the things we talked about sexually, bothered him. He was upset because he feels like I lied about not being sexual, given the things I would say to this guy after we’d have sex (telling him I enjoyed it, for example). He basically called me a liar, said I’m not who he thought I was, and that I’ve destroyed his trust. He told me he no longer considers me girlfriend material.

He’s now telling me that I’ll have to deal with the consequences of not telling him about sleeping with this guy. I apologized, but honestly, I don’t know if I’m wrong and I'm pretty upset he went through my phone and read things that had nothing to do with him since we've only known each other 2 months. I mean, since we started dating on February 14th, I haven’t met up with, kissed, or hooked up with any other guy. I understand that he’s upset because I didn’t tell him that I slept with this guy. Also, last night, I opened up to him about my feelings for him, my past, my fears, and everything else. His response was that it was all "bullshit" and that he doesn’t believe a word I said. However, he still claims to have feelings for me and says I need to prove why he should get over this situation.
