I'm finally free

Finally I got this guy online to break up with me. It was my first relationship and I regret it so badly. He was 4 years older than me. He first texted me about gaming and stuff. And soon shared many personal things. I understood that he was suffering and consoled him. From then on he just became so nice and caring. And when he confessed to me like two weeks later, I thought maybe this relationship would work. But he used to love bomb me so often. I was blinded by my love for him. I used to make myself believe it's fine. But he became so obsessive and intense. He said he wanted to get married as soon as possible and what not. I even blocked a guy for his happiness. But he would still constantly doubt me and think I'd betray him.
This all happened during my finals month and I was feeling so suffocated and emotionally burdened. I told him to either go back to being friends or just forget me. And when I blocked him, he texted me from another account saying he'd k1ll himself if I ignored him. He said he wouldn't let go of me and useless stuff like that. But I never told him where exactly I lived or any of my other socials so he was scared of me blocking him again.
When I bought up the topic of him isolating me, acting like he owned me he completely avoided that and he again said he didn't want me to talk to any guy online or make male friend like bruh. And he wanted me to stop talking to the ones I had as well. I told him I won't do what he told me to do and he acted like I betrayed him or some shit. He called me a slacker and blamed me for doing bad in my exams even though I didn't explicitly blame him or anything. I told him so many times that I don't love him anymore and that we're not compatible and many other things. He kept being dramatic and he finally said he needs time processing all this.
the next day he said have fun dating lots of people and some more useless stuff. and said he was tired of lowering his standard for me like bitch I lowered my standards for you, even though he was shorter than avarage men I still loved him for who he was and I regret it. and he even called me a filth who was trying to defile him and that I'll get the taste of my own medicine. I didn't respond and blocked him and deleted that account too. I feel so much better now. That worthless piece of shit was making me feel so numb whenever we talked. Thank God this one month of useless relation came to an end. I was such a dumbass to like a person like that. I don't know if I want to date anyone anymore. I want to focus on my studies more.
