((GracePeace)), I am sorry that you are experiencing this and it's confusing you so much. However, what I can tell you is that considering this man is suffering from PTSD and is a vet, his need for space has a lot more to do with HIM and his challenge than you. It's hard for someone suffering like this in that the one person they are struggling the most with when it comes to connecting is in fact "themselves". This is the biggest challenge when it comes to PTSD, especially when it comes to a vet. They really do suffer more than most can possibly understand, and this is why so many take their own lives every day. They are trying so hard to figure out how to restore themselves despite how often debilitating the PTSD can be for them.

How long has he been home from deployment? PTSD often develops once a vet ends deployment and it can get extremely challenging for a while often causing these individuals with withdraw.
