My husband and I have been separated for over a year and he lives in a different state. He is no longer in the army but I still am. we have still been getting BAH from the army and I just give him half. I started seeing someone else and informed him I would be filing for divorce. When he couldn't talk me out of it he came down here and took a bunch of pictures of me and hacked my iCloud. Yesterday he sent me a text saying he would report me to the army for adultry if I do not give him $5000. Is this legal? It feels very much like blackmail but I want to know what I should do about it.
