Hi Ahuva and welcome. I totally understand how you feel and I became increasingly angry with my husband when he would not respond to anything I asked him. In the end I would just yell out at him in the hope of getting any reaction at all, good or bad. Needless to say I always got bad. Since joining the forum I have learned a lot and realise I have made many mistakes. These mistakes have cost me my marriage, we separated 10 weeks ago. It may not be permanent but I don't blame him for not wanting to be around me.
My advice is be as patient as you possibly can and when you can't take anymore, go for a walk or do something nice for yourself. Or just go some where and scream and let it out. I wish I had found this forum a long time ago and maybe I wouldn't have made so many mistakes. I will never fully understand PTSD as I do not suffer from it but at leadt I do now know what not to do.
Good luck, the supporter section is very helpful and plenty of advice to be found.
