Ex Relationship

I have recently gotten out of a relationship. We had been dating for over a year, we started dating April of 2023, and ended May of 2024. For the first few months, it was absolutely fantastic, I loved him he loved me, I thought it was working. Later on, he started being boring and never wanted to do anything anymore. I ignored it for a long time. I ended up getting hospitalized in October (If you want that story lmk), and when I got out, he acted really different and weird towards me. Almost like he was keeping secrets. We started fighting a lot after that. He would yell and scream at me for hours over things I couldn't control. For example me forgetting things. When this pattern became repetitive, I started fighting back with him and that made everything worse. Usually I would just let him yell and I would try to fix things. He would constantly call me names and he would always brag about how much smarter he is and how the main things that make him happy is just being better than everyone. He never made me feel good about myself and always put me in the wrong. He was the biggest hypocrite I had ever met, he never even took accountability for his actions. Funny thing is, is that he always yelled at people for not taking accountability, so I would just laugh to myself about the whole thing. Moving on, we broke up because he was severely unstable and his mom had stepped in. My best friend told me after the relationship about how my ex would text him sexual things and it made him uncomfortable. When I read those messages, some of the things I knew, for example, me and my ex had mention a threesome and dirty talk, but my ex went to lengths of telling him "Don't tell Nat" (That's my nickname). So I told my friends and my friends spread it around. That wasn't my fault. My ex ended up texting me yesterday about the whole thing and was just putting me down and saying "This is your fault". I was just like "Okay whatever" at that point, but I did definitely tell him off because I was pissed. He ended texting my friend about how I was the reason for his drug habit and that I was a liar and a b!tch. He was saying how bad he wanted out of the relationship with me. It hurt so much to read but it also made sense as to why he was treating me the way he did. I'm still very hurt about it. Oh well, relationships come and go, I'm just waiting for the right person.
