I don’t think you’re being naive, but I would suggest doing some reading on the affects this drug has on an individual. It changes people and sometimes it can be a permanent change.
I do understand what you’re going through as many people on here do and I really feel sad for your situation. My family had it all once too. Lovely children, holidays, house, nice cars and good jobs. It doesn’t matter – cocaine always came first. They have to want help, and because that drug is so powerful it could be a long process.
You don’t have to leave him, however I warn you with this sort of drug you will be in for one hell of a ride. It nearly destroyed me and I am still picking the pieces up.
The lies, the let downs, worries, cheating and the list goes on. It gets worse as they get worse. In the end I was so focused on him that I forgot about me which lead to anxiety. My anxiety went through the roof. I started to doubt my self, blame myself and take on all his crap.
I found Al Anon and started to begin my own recovery which is another story.
What I’m saying is, when they are on drugs they ain’t the person you love anymore, that’s the addiction. Try looking at him as two different people – because the one you love is in there somewhere, however that person has to be more present than the other one.
The betrayal will gradually destroy you so please look after yourself.
Remember all addicts say they will change bla bla but it’s in the behaviour/ action! If he wanted to stop he could stop. He isn’t physically addicted he is choosing not to help himself.
