Welcome to the forum Andrea. It is lovely to have you.

Your husband does sound quite ill, however that does not mean you should have no expectations of him, and or that you should allow him to abuse you, verbally or otherwise. Calling you names is abuse, and should not be tolerated. Apologies quickly become meaningless, if he continues to do the same things over and over again with no attempt to change.

I would encourage you to ponder what behaviour you are willing to accept, and what behaviour you are not. Can you accept that perhaps one errand and loading the dishwasher is all he can accomplish in one day? He may truthfully not be capable of much more at present. However, I would NOT accept being called a c--t or other names, under ANY circumstances. That is most nasty and should not be tolerated. When he does it, tell him it is hurtful and walk away. Refuse to argue with him. It is difficult yes, but stand firm.

Examine yourself as well. Are you doing something to provoke him, such as constant nagging or laying guilt trips on his lack of activity? That is an easy habit to get into, and considering that someone with uncontrolled PTSD is in a constant state of stress, such nagging may very well be sending him over the edge.

Please do continue to post here, ask questions, and learn as much as you can about PTSD. The information sections of this forum are very helpful and a good place to begin. Above all do take care of yourself, your happiness counts and whilst you can support your man, he is the one who must heal himself, you cannot force him into that. I hope this new group he has begun will be helpful. Take good care.
