That relationship is so toxic and unhealthy

I've been in a relationship with a man for 4 years. It started off centered around drugs as we were both using. Within the first year I ended up losing my family my house my cars and had 8 charges and went to jail for 3 months. After getting out of prison the next two years were filled with drugs, constant arguing as there was so much distrust die to meth psychosis. The most crazy allegations were put on me and I felt like I was losing my spirit completely. In February 2021 my father passed away suddenly due to cancer and I decided to make a change. I moved away got a job was going to NA and started to feel good about my life again. We were still in contact however and I ended back there within 4 months. He promised to stop using drugs get a job and really make an effort in our relationship. Well that didn't happen. He constantly used methadone and pills and had psychosis from all the meth use. So I decided to leave again and packed what I could in my car. He was telling me he could hear people running around inside the house at night and that I had people coming through windows to have sex with me. It was crazy. The morning I left I woke up and noticed both tyres on my car were flat. He had let them down so I couldn't go anywhere. I got in my car and drove to the tyre shop and replaced them. I've been gone only a week and I miss him terribly but I need help because that relationship is so toxic and unhealthy. I really want to just go back and think maybe this time it'll be ok but I know it won't be unless we both get help.
