Divorce

So I’m confused on how divorce is a sin.

I want to divorce my husband. He’s emotionally and financially abusive. He can’t hold a job down. After our second set of twins, he lost his job while they were getting out of the NICU. I had lost my job during the pregnancy from being very sick. He told me I couldn’t be a sahm and we both needed to work. So I did food delivery until I found a full time job. The 2nd set was about 4/5 months old. They turn a year in May and he still doesn’t have a job. He then told me a couple of weeks ago that he was never actually looking and just wanted to stay home. My pregnancy was very rough and I had placenta abruption. When the younger twins got out the NICU he rarely helped with them. He still rarely helps with all the kids. I work overnight. I get off of work and as soon as I get home, he is handing me the boys. Like as soon as I walk through the door. The kids sleep throughout the night so he’s not up with any kids. I put the kids to bed so he’s not doing bedtime either. I nap when I can because he doesn’t watch the kids during the day. All he does is play Yahtzee with his aunt and dad or play on his phone.

I say all of this because I’m really confused. If I leave him am I going to hell? Am I just stuck in this for the rest of my life?
