It's time for you to step back and get help for yourself. If she's acting out in jail, she has no business coming back to your home. She assaulted you and your husband with with deadly weapons. She is way beyond your ability to help her. She'll only get worse with you enabling her, and your life will be hell, and there's a real possibility you and/or husband will end up injured, dead, or in jail.
You're saying she threw knives at you and your husband, fractured your husband's wrist, and he drew a gun. Do you see how it's not a good idea to let her back in your house? You're lucky this didn't end up worse than it did. Next time what happens, she charges you with a knife and husband shoots her? She gets ahold of his gun and kills you both? You need to step back from this situation big time. Bringing her back into your house is a recipe for disaster, for you and for her. Nothing good can come of it. Then you need to get professional help. Once you get some distance from the situation you will start to see how absolutely insane it is. I'm sorry you're in this situation, but like with our dysfunctional adult children, you have to make a decision that it's not what you want in your life and do what's necessary to change it. Nobody can do it for you.
