RANT: I feel let down and happy at the same time

So I was dating this guy and for the first year he was really nice. Then he started studying and he gave me less and less attention and I was like could you maybe give me more attention and he said I’ll do it after my exams and well I believed him.

a lot of things happened and my mental health worsened and well I kinda ignored it for a good while but the way he treated me made me have horrible panic attacks and idk he just started being very different. Towards the start of his exams I once again asked for more attention and he said he was too busy, but this time he stayed up past 1am making new friends (only female), when I confronted him about this he said I was being jealous and that I was overreacting and that he was allowed to make friends and that I was just being toxic. Well I don’t know why I tolerated this behaviour it got to the point where I just wanted to die and idk some of these girls he made friends with hit on him, and I asked him to stop talking with them which he did but he kaput asking how he could make it up to me so he could talk with them again because they were really cool and just understood him so well (maybe I’m over exaggerating but idk he played the victim which annoyed me a lot) and when I told him he could’ve told them he had a gf he just said no that would be annoying to them. Well fast forward he keeps this habit and I tell him my needs aren’t being met and that I’m upset with his behaviour that hasn’t changed at all like he said it would, he just starts yelling at me calling me toxic and jealous and then he asked if I wanted us to break up and I said yes I couldn’t take more.

anyway I’m really happy now but I’m also just angry. Like he accused me of cheating with anyone I became friends with, he wouldn’t even let me invite my male friend (who he made fun of for being gay) over so we could make cookies together, but it was okay for him to go meet a girl he made friends with less than a month after they became friends? And well idk he used to be so nice and caring and I was holding on for too long. He got upset over my dog, he called it ugly and said he wanted it to die because I loved it more than him, but at least my dog doesn’t lie to me and it loves me the way I am and my dog means a lot to me because it helped me stabilise my mental health and kinda make my anxiety attacks less bad. And idk every time I told him I was bi he was like no and I’m the end I felt like I couldn’t even be open about who I was or the fact that some of my friends were trans or non binary (I had to ask my friend if it was okay I misgendered them around him and I felt so horrible). I got diagnosed with autism during our relationship and I asked him to just read a little about it to have some understanding and he told me he wouldn’t because it didn’t interest him and it would be of no use anyway and I had to be crying before he said he would consider it. Anyway this is practically just a rant because idk man I feel so let down, I loved this guy and I feel so disappointed he turned into a complete asshole, we’ve been broken up for almost a month, my mental health has unproven so much my therapist said she didn’t know if I needed to go to therapy anymore and I’ve been seeing my friends more and I’ve even had sleepovers with them without having to worry about being accused of cheating and I’m so happy. He blocked me because I cut my hair in a ziggy startdust style and apparently that meant I cheated on him with my friend during our relationship and like idk I’m just over it and happy that he doesn’t speak to me anymore because he made me feel like trash ngl.

im sorry this is low-key just a rant I needed to let it go kinda
