Long story short-- my brother has a drug problem, been going on for ten years although there have been periods where he's either stopped (says he has) and seemed to be on the up. I cut ties with him over a year ago as we found out he was still doing drugs and he had sworn blind he had stopped. Enough was enough from my pov - couldn't trust anything he said. I was the only one to do so and tbh felt as if others judged I was being unduly harsh.
Since then he moved back in with my mum - parents split and live in different areas. Supposed to be temporary but obviously still there a year later. He constantly borrows money on whatever pretext he can think up, he pressures her with constant requests/demands to the point she ends up upset but gives him money ... I've listened to what's going on, obviously I no longer speak to him. I have told her she is enabling him, it's not helping and he won't stop- she has to decide to stop helping him although I accept that will be hard. I offered to speak to him and did contact him to ask we talk but he didn't respond!
I don't know what else I can do. I worry for my mum - she is getting on, isn't in the best of health and she should be relaxing and taking it easy. I can't force her not to help my brother, what more can I do?
