I need guidance on what to say or do! My sisters boyfriend has a problem with drinking and coke(which my sister has no knowledge of). He has no control over himself, once he starts he can’t stop. They have young child together who is only after turning one. They struggle to pay bills and I now have people texting me looking for money from him for bags of coke. He is a completely different person when he’s not drinking but I am absolutely sick of this now it has been going on way too long. My sister and my nephew deserve much better! I want him to be there for my sister and my nephew, I want to help him so much but I don’t what to do. I’m now begging for help before it’s too late.. What do I say? What do i do? How should i approached him about this?
