Your guy is combat PTSD, right? Might be different for him, but for me...
-being touched when I really don't want to be
-being guilt tripped when I need some space and time alone
-having to interact with people when their energy is just too much for me to handle
-being treated like I'm the bad guy for having these crazy issues
-being treated like I'm stupid just because I don't feel like interacting sometimes
Don't get me wrong...my DH is so incredibly supportive overall. But he's still a guy...a human being...and has his own stuff to figure out, too. And not all of this is in reference to him...my family (mom, sisters, etc) are very dysfunctional and don't know how much of this stuff is going on, so they tend to trigger problems without understanding the big picture of why.
