Just to clarify - your husband is the problem drinker and you are not a problem drinker?
Are you happy that he has left?
To me you sound quite bewildered and in shock.
I experienced a similar situation when my ex left after 12 years together.
I felt that I did not understand the world anymore.
I did not understand how one human being could do that to another human being.
I constantly looked at other marriages and couples and wondered what I had done wrong and what was wrong with me.
I realised I was suffering from emotional shock.
Psychological shock, a form of psychological trauma, is the body’s very real stress response to experiencing or witnessing an overwhelming and/or frightening event.
Please ask for help and please keep coming here.
Wherever you post, you are in the right place.
I wish you the best xx
