Roses, I don't think anyone here is excited about your pain, I think we all feel for you and are concerned for you and your family's future. No matter what happens, you and your kids will survive. There's government assistance for a reason. You will make it through this whether he's convicted or not.
DUI refusals are not hard to prove, law enforcement is trained to spot the signs, and their testimony in court is usually very convincing. I'm not trying to be negative, but I work for a law firm that specializes in DUIs and divorces and my AH is a cop so I'm very familiar with it. I hope that your husband gets the help he needs and I hope only the best for you and your family. I know it's hard, but you have already been so strong, you'll get through this.
