Hi poppy1234, hi Ambaj24 ,
Reading your messages has reminded me of my 4 year marriage with a Narcassist and a cocaine/alcohol/weed addict . I lived on the edge. His mood swings his manipulation his demand for sex , the arguments the financial problems. I stressed myself out to the point i became suicidal. Bottom line is If he doesn’t want to change himself then there is nothing you can do to help. You will live a miserable life with him even though you are the victim you will be made to believe you push him to drugs etc.
most likely he will cheat and go on dating sites and watch pornography.
Best thing to do is leave him
