My husband has recently told me that he isn't happy in our marriage.. And he seemed so fine last week. I didn't see any of this coming. He says he's not happy with anything in life. But he's pushing me away.. He said he just wants to be alone. That he needs to find himself and find happiness. And it hurts me that I can't give him what he needs. And he's being very stubborn about going to talk to anyone. And he doesn't know how to explain to me what's going on with him. I just can't lose him. And I need to know more about PTSD and what I should and shouldn't do. If anyone has any advice it would be greatly appreciated. Thanks in advance.
