aita for breaking up with my ex after his mum just got out of hospital?

this happened a while ago me and him have been broken up for some time now but i want to know if i was in the wrong? for some background information me and this guy who im going to give the name "daniel" had dated two times previously so this was our third attempt of giving it ago and seeing if it would work out, previously the two other times he was the one who would always break up with me and still get in a huge fucking pissy over it and destory things that i made him on his snap story after we had ended or had an argument looking back i realise that this behaviour is now kind of toxic. during our third try at the relationship we had been dating for around 4 months when his toxic tendecies started to play up again he would hit me for no reason on my right knee and i have problems with this knee as my ligament at the back of it is damdged and iv had an MRI scan for this too and even told him about my damadged knees thats why he would hit me in them. anyways he was also very verbally and emotionally abusive i had to keep going to the GP about my mental health and weight as i was classed underweight which i had told him i was underweight and i also had body dismorfia and an ED it was a shit time in my life and his exact words were "the scales must be lying, your a fat fuck go and hop on a tredmile" which of course hurt me a lot at the time due to my insecurities and low self-esteem and low self-image. Around the 5-6 month mark of our relationship i had gotten a call from him at around 2 in the morning saying that his mum had overdosed and is being sent into hospital and asked if he could come round to my house, i was very confused and still half asleep but i knew for certain my mum would be mad if i woke her up so i simply told him that my mum and dad and my two younger siblings who are within the ages of 5-8 were asleep and he cant come over, he then yelled down the phone hung up and called my mum waking her up and she said the same thing that he cannot sleep round and she is extremely sorry. The next day his mother had been released from hospital and everything was back to normal until "daniel" started to be his usual self again and started saying cruel shit about his mum, one of the things he said was "i wish she would have died that night" and i told him that behavior was unacceptable and that she is his mother and brought him into the world and he cannot be speaking about him like that, as his mother truly is a wonderful woman, but as time past he just became more distant,violent and extremely cold towards me and i didnt know what to do i was literally at my breaking point, my mental health was a shit show and i was all over the place and i didnt know what to do anymore, every conversation we had he would turn it into a full blown out argument and i couldnt cope with it, i know he was going through a lot and i appreciate that and i tried as best as i could to help and support him i really did but in the end 2 weeks after the incident had taken place i couldnt deal with it anymore and told him i want to break up which he did not like at all and then he blocked me on all social media platforms but this shit show does not end there! we both attended the same high-school, hes left now and im in my last year but still he had made 2 snapchat storys all about me spreading rumors in them saying im a cheater and that i tried to get with his old friend and that im a ugly slag who would spread there legs for anyone and that im also a gold digging bitch, which i ofcourse was pissed about because none of it was true and it angered me so much and also upset me a great deal at the same time because this was a boy that i used to love and care for but i brushed it off and told my head of year that i need to sit in reception or something because i was going to hurt him or myself from how absolutely pissed off his lies made me, at the end of all of this police got involved and he had a stalking case against him.
