I'm so sorry you are going through this. His treatment of you in your own home is appalling and I see no reason for you to tolerate it. 'The first thing to do is to take care of yourself. I make the following suggestions:
1) Copy the file and put it in a safe place in case you need it. 2) Tell H he cannot keep using his computer in your home. He crossed a boundary and you need to protect yourself by respecting yourself. 3) Remove yourself from any shared credit cards so that you are not responsible for the costs of his A. (Average cost, $25,000 I believe.) (Trust me, the old promises about supporting you through grad school, if made, in all likelihood will be broken.) 4) Change your locks or ask for his keyes before he takes his trip. He is no longer acting like your H and should not have access to your home as if he is your H. 5) If you can't stand not reading the emails, don't involve a friend. Use Babelfish. 6) Spend more time hanging out with your fellow grad students and enjoy school.
