AITAH? I lied to my boyfriend about a date I went, when we were broken uo

I lied to my boyfriend about a date I went on when we were broken up.

My boyfriend and I broke up because I had lied to him about my first relationship. I was 19 at that time and did some stupid things to broke my parents trust so I had promised myself that I'm not gonna tell anyone about it. about 4 months ago, my boyfriend of 2 years found out about it through a chat history I had with chatgpt. He asked me to tell.the truth but I lied to his face. So we broke up. But this year, he had given me another chance to be with him.

at the time we were broken up, I had a interaction with another boy. we went on a date. When I got back together with my boyfriend, I didn't tell him that I went on a date. Then yesterday he again found a chat history where I let out my thoughts about the date I had, and asked me if that was true. After reading the whole chat, he said that I was putting myself out their already like a slut and he doesn't want his future wife to be like me or mother of his children to be like me. He said tht he couldn't trust me anymore and he would wanna have sex with other women to feel what I felt. The last thing he said to me was that he doesn't want me near his sight and would tell me what happened between him and his potential next girl who he wants have sex with(he let me pick two girls who already wanted him).

I know i am in fault here. I know i deserve it. I know he deserves better than me. I don't know how to live with this. I haven't had sex with the man I went on a date with.

But I understand how it feels. It feels like betrayal. We broke up this morning. I am gonna leave him alone. I made mistakes and I know I have to face consequences for my actions. I don't wanna hear what he did or would do with these girls, but I don't know what to to do. I feel like a whore.

I am not here to ask whether I am the asshole or not. I am definitely the asshole. I just wanted to confess what I did and I don't know how to fix myself from doing bad things to break other people.
