As hard as it is maybe it is time to let go. There comes a time when it just isn't worth the hurt and anguish anymore. Use the support of your friends to help you through the tough times. Get out before it destroys you. Maybe when he is over having his fun and pretending there is nothing wrong with him, he will make contact again. Until then, work on you so that if he comes back you have a better idea of what you want and what your limits and boundaries are.
I know how hard it is from my own miserable experiences. I hit rock bottom myself, plunging into deep depression and wanting to end my life. If it weren't for my family I possibly would have done it. All because my sufferer treated me so badly and showed no concern for how hurt I was. Sure, PTSD may have played a role and maybe he couldn't help it, but it was destroying me and 28 years together made absolutely no difference. At this point your sufferer knows you are there waiting for him, accepting all he is dishing out, don't be his doormat. You deserve so much more.
