Wow. Sounds like you are both going through a lot. Is it possible he suffers from Post-Traumatic Stress Disorder? I suffer from complex PTSD from other issues (I did not serve), and it makes things extremely difficult, especially when you are going through the worst of it. I know this is fairly common amongst those who have served overseas.
I don't really have much advice for you as this is a different situation, but GAL is always a good idea. And protect yourself and your family. If that means getting a full-time job despite him wanting you to stay at home, so be it.
It must be so hard for you right now, worrying about his safety and well-being while also going through marriage issues. Hold strong and work on yourself, not for the M, but for YOU.
