Stuck in a bad marriage how do I get out?

I don't know where to begin. I am married to a liar. My husband lies about everything to me and as a result there is no trust in my part now. I came into the marriage with no debt. I had a perfect credit score. I was living on my own, paying my own bills and doing alright for myself. We met and he proposed to me, got married and then moved in together after we were married. I was working at a bank making my own money but the job was stressing me out. I faced racial slurs at work and my blood pressure kept going up. He was into trucking and making good money so he told me if I wanted, I can quit the job and then later on find something I would enjoy doing. This man was making $1500-$2800 per week. No taxes were taken out. He was supposed to do that because he works for a small trucking company. Needless to say, he wasn't setting aside any extra money for when tax time comes. Even tho I told him to and he said he was. Around Dec 2022 I quit my job. Jan 2023 I found out I'm pregnant. After that, all hell broke loose. He lost his job because of stupid things he was doing at work and the boss got tired of him. He then told me he wanted to start his own trucking co. The man went behind my back and bought a whole dually truck for $30k and drove him with the truck. Come to find out, it was a lemon and the idiot didn't get any warranty on the truck. In 30 days the truck engine blew up. He fought for months with them and nothing. The payment is sky high on it. He had them repo the truck and now has to pay back a truck he doesn't have. He then went behind my back again and bought another truck with all his savings for $10k cash from a private seller. The man sold him a lemon. That truck caught on fire on a PA highway. Then gonna ask me to use my savings to help him get a third truck. It gets worst. Tax time comes and we filed jointly. Come to find out, this man owes the IRS over $18k from previous years and because he added me to his taxes, I am now responsible for that balance even tho it has nothing to do with me. Last night I found credit cards maxed out with cap one for $6k plus and another bill for sea-world for $200 that went to collections. We've never been to sea-world together. He got into an accident in New York that I didn't know about and hit a guard rail. Apparently it's property damage of the state. So he owes them over $4k. The list goes on. We have a 14 month old son together. I have no education, no job, I don't even have my citizenship. We are in the process of filing (of course I'm using my savings to pay for it). I have no family that would help take me in because no one in my family speaks to each other. I honestly feel like I'm gonna have a heart attack. I'm so lost, I don't know what I did to deserve this. I would never get married again. Never. I have always been honest with this man. I tell him everything about me and my past. I love to communicate and I didn't get they in return. Married to a complete stranger. I want to leave but if I do, my process will be messed up. I'm stuck in a bad place. I have no means to take care of the baby on my own. I have nothing. I have $3.06 in my checking account. Because he doesn't give me money.
