my husband has always been a trigger & instigator of my ptsd also..

mostly out of misunderstanding & ignorance/arrogance to his own dysfunctional upbringing & therefore has trouble controlling it...
he is aware on the surface that he is really terrible for my illness... but he doesnt truly get the impactual longevity of his behaviours on y psyche...
i cant heal my old traumas because im trying to cope on a daily basis with my new [re?]traumas from him...

maybe she could go to counselling with a specialist or yes if she was committed to the effort, she may choose to read the forum here?
