I'm prior military so....Actually no he doesn't have to be there. All you have to do is talk to his CO or go to the S3 and talk to them. They will give you the paper work you need, and should sign off on it. Do you have a phone tree with a list of all the other wives who should be there? Your CO's wife should be able to help you.
Also I know what you are saying about your H wanting the single life. My W is like that also. She has surrounded herself with people that are 3 to 4 years younger than her, none of them have children and all are single. She honestly wants to be 21 or so and have that life of partying. we got married young and all of that. The thing with me is that I know the mistakes I made and I have been taking the baby steps to correct them. I want my marriage to work. And I'll put the work in. I honor and take my vows seriously. Hopefully if I can become a better person for myself and I make the changes for myself I will be the best person i can be. It is all about you and you making yourself better not for him but for you. Everyone on this site will tell you that. I have been told it a hundred times so far and i'm sure I'll hear it a million more. Make sure you can stand on your own two feet with your head held high.
I know you want to be able to say that you tried everything and right now you are in the midst of trying. Don't give up, even if leaving back to the states might feel like giving up. You ask where will you be when it happens? When he finnally opens his heart and his eyes? You'll be a strong and confident person, if you work on you. That is all you can do. I was told that only he can make himself work on your R. So find hobbies if you decided to stay. explore Turkey you are in one of the oldest cities in the world. You have a lot you can learn there. Find people that will go with you and just take in that culture. Keep your head up!
I like all this empty space because i can now type out things that are important.
