Very sad situation on top of an already sad situation! My heart goes out to you. Don't let him hurt you after all the ways you are trying to help him! That is totally unacceptable. Does he realize if you leave, it's him, his PTSD and a woman who won't even give a crap? Let HER see him when he has a PTSD rage. Tell him to take it to HER. Let's see how long THAT lasts!!
