This is the guy who wasn't actually diagnosed with PTSD? Who you just assume has PTSD? Who told you he was depressed and needed time cause he hadn't yet grieved the loss of his 10-year marriage? I'm sorry, but I still think you are jumping to conclusions here about his "isolation" being from PTSD and not just a natural need to think about the relationship or get over his last one. To be honest, as a PTSD sufferer, I find it slightly insulting that you are attributing all of his behavior to PTSD when you admitted that he never actually said he has PTSD, nor was he ever diagnosed with it. In your previous posts, you said you "thought he might have PTSD" because he had a hard time talking about emotions. There are enough stereotypes about PTSD already, so it's sad to see PTSD being blamed any time someone has a hard time with someone who has served in the military. A man said he needs time to think? Gee, must be PTSD, it certainly can't be anything normal like actually needing time to think. If he really does have PTSD, it's even more insulting, because then it's like saying his request for space isn't valid and is just a symptom of a disease, not something to be taken seriously. For Christ's sake, he just found out his son is developmentally delayed and he's being sent overseas so he won't be around to help his own son deal with this .... that's enough for anyone to need time to think, and here you are projecting fantasies of PTSD onto the guy instead of taking him at his word. I realize the whole situation came as a shock to you and you crave some sort of explanation, but from your posts on here, I get the impression that you simply refuse to respect the explanation he already gave you, and are instead looking for some alternative explanation that will make you feel better. It just seems disrespectful and invalidating towards him for you to do this. I know the anxiety can't be making it any easier, and maybe that is making you overthink things. But it seems like the more you obsess over the situation, the deeper you dig and the further you become from just accepting things, respecting the guy's needs and focusing on yourself. This is just my opinion and I may be wrong, obviously, I don't know the guy like you do. But even regardless of whether or not this guy has PTSD, you definitely need to focus more on yourself and stop obsessing so much, find a hobby or something to channel all of this anxious energy into.
