I apologize for not having responded sooner, simply very busy. Before I do respond in full though, I wanted to ask: have you asked your husband directly what he wants? Have you asked him how often he wants contact with you, how long he wishes the separation to be, how much help he wants from you and so on? It is a different matter if you have already asked and he doesn't know or refuses to tell you, however if you have not directly asked him, you will be giving yourself much grief trying to guess. We carers are not mind readers! Additionally, he is an adult and the decisions he makes must be respected, regardless if he has PTSD. Yes, those with PTSD do well with an understanding carer, however only if they truly want the help of said carer. If they don't want the help and it is pushed upon them, they tend to withdraw even further. It boils down to, you must know his boundaries and he must know yours, and you must respect each other's boundaries. That is something you must do in any relationship, PTSD notwithstanding.

I noticed you asked this question of the sufferers, well done. I do hope they can give you some insight. Know however that each situation is unique. It is ultimately up to your husband to tell you what he wants.
