Also figgure out if and how much you truly love her... after reading all you can about PTSD and put aside as much of the things that have been said and done as you can. Do you love her as a person.. and love her enough to stay with her through all this and the future hard times to come? even with help and therapy it will be hard. If you don't think you can stay with her.. then don't stay out of guilt or feeling like your just giving up. If you don't put your whole into it then you most likely will be hurting her more in the long run becouse she WILL feel that lack of love.
