How Can I Fix This Relationship Problem To Get My Parents To Like This Man Again? And Get Him To Like Them?

I had a boyfriend who I have been in love with for over four years
About a little more than a month ago he broke up with me because I wouldn’t stand up to my parents. Before this happened, I was late to a dinner plan due to school reasons and then he wouldn’t let me inside the house and he just glared at me through the glass door. My feelings were hurt and my parents were so enraged by his actions because they thought he was only interested in having me over on time to have sex with him. They gave me a last chance offer with him that we could meet halfway for our dates and never go inside each others homes (to avoiding doing it) until we are ready for a financial commitment on our own. This will prove that his love is real to them. He then asked me to marry him to prove to my parents that he loved me. This made my parents even more upset because they feel he is trying to get control of me. The next morning he called me, apologized for proposing to me and said we shouldn’t see each other anymore because he is not going to be treated like a 16 year old. My parents said that he is abusive and they don’t want to have to arrange my funeral me someday. Therefore, if I even think of going back with him, I will be disowned by the whole family.
A couple of weeks later, I text him and told him that I wanted to be friends and he called back saying he still has feelings for me. I told him If I go back to him, he and his parents will have to take care of me because my parents will cut off all forms of support from me. He promised he would get a job and find all the answers to supporting me because he loves me. His parents told me whatever he and I do, they will not be involved because we are two adults making to adult decisions, but they assured me that their “son loves [me] and would never harm [me]”. I’ve attempted to pack my bags and leave to his house. I realized I would have had no health insurance, no possibly education, no car, but I didn’t care. My mother bawled and yelled at me how much I was a faker to them as I was packing away my belongings and my dad was acting like he was going to have a heart attack. They took from me everything the family got for me in which I was OK with. What was challenging was that I had no way of calling my ex and telling him I have been kicked out and need a ride. I struggled out the door with a lot of my belongings. My mom continued shouting to me as I kept trying to leave the front of the house at 9pm. I couldn’t stand the thought anymore that my loved ones were hurting all because I want my boyfriend back. I came back inside and called my ex to tell him what happened. He asked “did you get kicked out yet?” I replied “Yes, but I had to go back inside…” He said “Then I guess you really don’t love me. I guess it really is over.” I told him it wasn’t true and he told me he did not want to hear it. I made him promise to me he will be alright without me. With anger in his voice, he told me he will be fine.
A couple of weeks after that incident. He started leaving me messages through holes where I did not block him (youtube) telling me that he was getting over me before I texted him, but my text brought his feelings back and he can’t rest until he is sure he wont hear from me again. I couldn’t promise that so I didn’t reply. Later he sent a comment saying that he wants to forget me but he can’t. Eventually he called the house and when my mom picked it up he shouted “**** you! **** you all!” and hung up. (She was going through mourning at the time because her brother died.) At this point a good portion of me thought he was dangerous so I went along with my parents suggestion that I should tell the police that he might be a threat. So I did… It was hard, but the police made it so my ex can’t contact me or I cannot contact him or harassment charges will be filed.
Now today, I feel quite depressed still. Part of me feels there is SOME abuse present, but I don’t care anymore. His rage issue are only a result of his disability and the trace of schizophrenia in which he takes medication for. Another part of me feels like I went wrong somewhere along the line that made my ex change for the worst. However, I think his bad qualities of him won’t be even close to enough to say I will end up unhappy or dead if I was still with him. I know he did a lot of cruel things during this process, but they can not outweight the good times I had with him throughout the years. I do regret getting the authorities involved because it badly burned our bridges. I could have called him back instead and explained that it wasn’t a good time because my mom was in mourning.
In a nutshell, he hates my parents because he thinks they are controlling me. My parents hate him because they believe he is abusive. His parents hate my parents because they accused their son of being abusive. And my parents hate his parents because they ne
