Help me Leave or Wait, I cant do this to much longer

After how many years of not being married do u leave. I have been with this man for 7 years of my life, the first 4 we were heroin addicts.. I met him when I was 18 and he was 25. After we got sober he didnt want todo anything anymore. I couldn't get him to goto a beach until this year. N he still wont go swimming with me. I broke up with him for a while in 2018 to 2019 while broken up we were still having sex, he has always wanted a baby and while broken up I got pregnant. I thought he would change and he kinda did just he got motivated but only for the baby. He finally got a job but only for the baby. I dont ask him for a dime, yet he is telling people I'm sucking money out of him. He is telling my parents that my grandparents think I'm a scumbag and calling my grandparent's telling them, I'm a horrible person. I have stuck threw this relationship so long that it's done a lot of damage he got a possession charge and told the cops it was mine. I wake up every morning at 5am so he can make a lot of money at work, I'm not talking minimum wage. He has ran up bills in my name and let them go against my credit. N just tonight I brought all the groceries its 2:40am and he wants me to put them away because he has to sleep for work. I get 1 pack of cigs a day and recently I haven't even been getting that. I can ask him to goto the beach even if I offer to pay for it. He doesnt wanna go anywhere. I had a baby with him though and now I feel trapped. I'm pretty sure he has tried to trap a few women in his past by trying to have a baby. I was on birth control when we had my son. While I was pregnant I made it clear I wanted my baby to have my last name, but his father and grandfather argued with me. They told me we would be getting married right after the baby was born back than i thought it would be best for the baby. Now I'm realizing that it's just been harder on me. Since I did that my "boyfriend" to me has seemed like he doesnt care about me at all and just wants my son. N me to take care of him when he goes to work and he has been very aggressive to me. The first few months I had postpartum depression but the "boyfriend" and his father didnt help. If I wanted to take my son to see my family they would tell me no because my brother was in school and my parents worked retail. I'm sick of this, all I have is my words now and he wont even listen to me he will walk away. Turn up the radio and if I text him about this he says I'm crazy. I'm worried about leaving because even though he lives with his father he still has a house and I dont. I cant get income housing with him on it, Especially since he is working. N since he is working and has a lot of money I'm worried they will get a good lawyer because they already are saving up money. I am itching every night from stress from him.
