Andrea, take the above advice. We with PTSD push those close to us away, because we often have convinced ourselves that we are only bringing everyone around us down with us. That is not true, it is not reality, but we believe it when we think it enough. We do this even when we love them so much, and don't want to be away from them, we do it anyway.

You need to talk about this, reaffirm to one another that you are both committed in getting past PTSD, from your side being support, and his being to get treatment and education on managing PTSD. It is a two way street, no different from just marriage itself. PTSD or not, relationships are two sided, and both sides need to come together. Every relationship has its up and downs, but it doesn't mean seperation is the answer if you both still love one another.
