It is very hard Mnon when you are trying to support someone through their addiction. I’ve tried all sorts of things to help – checking him into rehab, locking the drinks cupboard, getting rid of alcohol from the house, having people over to ‘babysit’ him so he can’t go out and buy booze – but none of these things matter because the addict has to want to change himself, nobody can do it for him.
I noticed that you said you’re the wage earner, so are there some boundaries you can set with your money so only you have access to it? If it’s your money, you should be the one in control of spending it.
