Oh no, I don't think you're a cow. I had someone do that- where you felt terrible suspecting them of ulterior motives for their 'kindnesses' because one KNEW the pattern behind them previously. Isn't it awful? It just used to make me feel tired, and hopeless and depressed/frustrated/manipulated. Mine was a some different since there was also rampant abuse involved, with the attendant 'excuses; and 'good' behaviour. His was 'the alcoholic in him made him do it'. Oh- ok. Well if THAT'S the case go ahead and beat the crap out of me, it's just FINE!!
It's the pattern that does 'get you', I know because in that IS the manipulation and that just hurts. ou know that when the necessity is over, the old stuff will be right back until next time he needs the kudos. Yes, someone with PTSD does tend to become overwhelmed with a lot of noise and chaos. Someone with PTSD and 5 children does not have to be hurtful to his wife. 'Shut up' is never acceptable, and no wonder you cried! It sounds like you have a very good understanding of his mind-set, and being here must be helping you acknowledge the things a PTSD sufferer really might have to deal with and what he uses to excuse crappy behaviour.
There's always the 'maybe' that the therapy will go well, I know. It would be nice if the expectation that he's just going to try to manipulate that, too would be wrong. At any rate, you're 'allowed' to say whatever you wish to here. :) If it doesn't help help 'change' him ( only he can do that, and he seems resistant... ) at least you can leave some of your stress here on a page or two. I log on when I can't make sense out of anything much( which is a lot ) since something about it helps make sense of the chaos for the day.
