When you have a continuous, unstoppable problem, the only solution is the authority to stop everything!
If you love that person you would like to help, you will do everything to prevent them from causing more problems, you will have to do what is necessary, make them stop
immediately! With good or bad manners, if they don't want to listen, it means they don't need your help!
Exactly, there are people who only listen to themselves and never to others. I'm not saying that's bad, but there are situations that requires you to listen and check what others are telling you, and if you see that they are right and their opinion is worth noting, then you take the opinion and put it into good news. But some persons never listens, no matter how much you try to talk to them.
Yes, I know that addiction isn't something that just goes away like that, but at least one should first of all put his mind to it, let it be that you're trying and failing, than you're not trying at all. No matter my relationship with such a person, I'd find it very hard to give such a person financial assistance.
