Why not write him a letter and give it to your lawyer, let him read it and give it to your husband. This way you let him know what you want and what you are willing to do. I know you miss him, and want to speak to him, we all miss our love one, not the addict and want to speak to the person they use to be.
Take the time to think what is best for you and your girls. In NJ it takes 18 months to get a divorce, so you have time to change your mind. Don't worry about the lawyer bill right now, worry about what you have to do for you and your girls.
