how can I move back to Texas with my children while separated from my husband?

My husband is in the US Army and we want to divorce. He is also foreign. He is planning to get out of the military and move back to Australia in the coming year. He has told me I can’t leave the state with our boys yet all my family is in Texas not here and he is planning on leaving anyway. I also haven’t worked in eight years and have depended on him solely for support. He has been throwing that in my face, like it is my fault he joined the military and we had kids. It was his idea that I stay home to save on child care. He is making this very ugly. So what can I do since I have no money and my family is far away?
