Need advice on how to deal with my unsaved husband. Am I allowed to divorce?

I became a Christian 4 years after being with my husband. We’ve been together for 20. Throughout the years he has extremely verbally, mentally, emotionally and financially abused me. He has called me every name in the book, said I wasn’t a good wife because I wouldn’t submit to absolutely everything he said or wanted me to do- wouldn’t let me see my family, prohibited me from going to church which I went anyways, i was to accept him yelling at me and being condescending, he gaslights me, blaming me for his outbursts and him hitting the walls till his knuckles bled- no he doesn’t hit me- he has come home multiple times smelling like a woman and denied he cheated, he left me multiple times in the past with no gas so I wouldn’t go out, he has my neighbors watching me and report to him when i would leave and come home. Had cameras in the home without telling me but I found them and he supposedly took them out. He has absolutely no interest in becoming a Christian although once in a blue he’ll go to church with me. It’s been an absolutely agonizing marriage. Im so done and tired of all the abuse. My daughter even told me to divorce him because he treats the kids the same way. I do pray, I fast, I play sermons and worship music, I anoint my home, I’ve tried to change my ways and try to be a Godly wife thinking it was me but it’s been the same even with me showing more love, being on time with food, cleaning the home etc. it’s been a very rough 20 years and im absolutely exhausted, mentally drained, and very unhappy. I never fell in love with him. I settled for him. I saw the red flags in the beginning and should’ve left immediately. When I had my two kids he threatened to take my kids away if I ever left him. I stood because of the kids. They’re now older teenagers who see the abuse. He has a huge addiction to porn, doesn’t want to have sex with me which im absolutely okay with. I feel disgusted when we are intimate. Im a sick woman, with multiple diseases and he doesn’t care for me, doesn’t show affection nor help me. My body aches everyday. Yes I do work. I have to otherwise my kids needs wouldn’t be supplied. He doesn’t always supply all the needs of the home. By the Bible am I allowed to divorce? I’m so done with him. I’m even willing to be just alone the rest of my life. I can’t trust men anymore. My dad and brothers were abusive too. Im just so done with this marriage. I need advice please.
