He asked for divorce after coming back from Iraq..

[A&J2009]

I don't know what to think now, we talked on the phone a couple of times and then after the last talk he wrote me a message saying if I really want to try to work things out we should have an honest period and I should write him a letter honestly saying what I've been doing all this time we were apart and he is ready to be honest with me to work things out and grow together. and even if I cheated on him he would try to get past it and work on it, stuff happens( the way he said it), and he said- I'm willing to work on myself and us if you are too.
So I've been writing this letter for a couple of days, honestly told him everything I've been doing, and promised that no cheating ever happened and said that Im happy to know that he wants to work on himself and us together. I sent the letter on Monday night, today is Thursday morning and NOTHING! Not a word from him, and he said he's willing to work on us and disappear. I'm so afraid he's done that just to find out what I've been and that's it, but on the other hand why would he want to know that if he didnt care. I texted him last night, said I hope he's work is doing good and I'm thinking of him and asked him to let me know when I can call him to talk. Never got anything back! I called him today twice and he didn't pick up! I don't understand what he's thinking and doing, feel like its another test for me but I can't figure it. I'm going to California in 4 days already and I want to let him know I'm coming before I get there but he's not even answering! I don't know what to do?!! Help!
