Welcome to the forum kaytiej. You've asked quite an enormous question. I suggest you read this forum thoroughly, especially the Information sections, and learn everything you can about PTSD. Knowledge is power, and as a family member I've found the more I learn the better I am able to cope. Communication is vital. Talk everything out with your boyfriend as openly as you are able, and be truly willing and open-minded to his feelings and requests, even if they seem silly to you. Know also that your boyfriend is the only one who can truly work on himself to heal. Friends and family can be there for support and guidance, but the person with PTSD must do all of the legwork themselves. I wish you good luck!
