Am I wrong for breaking up with my ex and?

I was dating this guy for 3 years and he will always give me the silent treatment when he was mad. My birthday was a few months back and he told me he is planning something. I took 1 week off work. The week before my birthday he created an issue about me not knowing how many people were missing from the Baltimore bridge that collapsed. I am a neuroscientist at the hospital they were brought in but I do not know anything about the trauma department. I did not understand the problem. The rest of the week, he will ignore me not talk to me but answer calls in front of me. That Thursday he messaged me he was going to a town 2 hrs for work (he is a private investigator). her dodged my calls the whole weekend. I tried to find out the issue but he will angrily yell at me. The night before my birthday he told me he was staying at his parents house who leave 3hrs away. On my birthday he did not call nor text me. He came back the day after and we spoke and he told me about family issues that happen which is why he feel the way he does. Few days later I find a receipt from MK swim short bought by him on my birthday in Florida and and I asked him about and he lied to my face and kept blaming for wanting attention. In the mean time I had found out a lot of other things. and he made me lie to people about his job. I told him that night we were done. And he was yelling at me saying he knows people who can hurt me. I was scared for a while as he looked like he could turn violent. I messaged him to get the rest of his stuff and told him I will bring them to the lobby as I am scared to be alone with him and he lost it. He told me he filed a claim court for the belongings (socks, remote control and cord of printer). Its been months and I never received anything. He keyed my car and I am scare and don't know if I should trash the belongings. I am scared he might tried to hurt me if I do. Any advice on how to proceed.
