Legal Advice

Hi, I'm in a bad situation, and I really am at a loss of what do, which is why I'm resorting to reddit. I haven't even heard of this site until a few days ago, but I'm desperate. My fiancé and I have been together 3 years. During those 3 years, he has been an angry and abusive man. He's never hurt me, but he was very abusive to our animals. I always tried to intervene when I could. But a lot of the times it would happen when I wasn't home. Anyways. He's worked on his anger and how he treats people, and is a different person now. He doesn't hurt the animals anymore. However, that doesn't even matter to me anymore. Like, I'm checked out - done. And he doesn't seem to understand that. He's saying that I will NOT be taking the three dogs, despite me begging to do 50/50. He said if I take the dogs, especially Romeo, our french bulldog, he will call the cops on me and have me charged with a felony (since if you take something over $1,000 in South Dakota, you can be charged with a felony.) He then said that I would lose my job because of that, since you can't work where I do with a felony. I bought our french bulldog with my credit card, but I believe the papers we have might say his name. I'm not even sure where they're at. He recently took out a 20k loan to pay off his, mine, and his brother's credit cards. Which I am helping pay that loan back. But because of this, he's saying I technically didn't buy our dog since he paid the credit card off. He also then drained our joint bank account that had over 5k in it. I don't even care about the money. I just can't abandon my dogs. I love them so much, I can't even express it. Our three dogs are Callie, Caesar, and Romeo. Caesar, a great dane, is his dog, so as much as I want to take him with, I can't. I adopted Callie, a black lab, through a humane society, and I bought Romeo, a french bulldog, at the local pet store with my credit card. So I hope I can take him. I didn't want it to come to this. I wanted to do the animals 50/50 because I don't think it's fair to do that to the animals or to him. I don't know what to do. I feel so scared and trapped. I feel bad because I know he loves me, but I'm just checked out. Any advice I would appreciate.
