Sorry to hear about the sadness that has befallen your brother and his wife.
Quote: He lives in a city he does not particularly like, has a job he dislikes and is exposed everyday to all sort of pressures...
I know that my H's high stress job was creating an enormous amount of tension which allowed toxins to seep into our riddled relationship.
Quote: Add to that the death of most of his family (only his sister is left) in less than 5 years
The loss of most of his family members in such a short period of time must be very difficult for him - and for you.
"Being controlling" is an issue that has taken a long time for me to come to grips with...and still gripping. I never realized just how much I fed into my H insecurity, how much I dragged my nails down his pyschological blackboard, until I started doing the "work".
I think that you are doing the most loving and healing thing possible by graciously giving him time and space.
I am deeply impressed by the standard you have set for yourself, and the strength and grace you operate from during this trying time.
