Hiya danni.. im same as your bf but with a coke problem. Im having it once a week. But im doing my very best to stop. Ive tried loads of things.
The reason he starts the arguments for nothing and then uses it as an excuse to drink or use is called.. emotional relapse.. this is what the brain does to us because its craving the alcohol or beer. So he needs to do things to prevent these situations. Or know what his brain is doing.
Alcohol is a main trigger for coke. The minute i have a beer, i want coke and thats most people who use coke.
But if you want him to stop having it , he has to want to quit it and admit he has a problem himself.
Have u mentioned this to him about getting help and fix things?
