Yes, it was, nothing to do with him wanting to die - the reason he has not told anyone about the 'PTSD' is that he thinks he will be prevented from active service, and he doesn't want that, he wants to keep his income for the sake of his kids.

Looking at that summary, I reckon Kelley Hawes is deaded.
