So my partner of 4 years recently started taking cocain in the bath room every time he gose through I can hear him. This only started 3 weeks ago after we had a break for 2 weeks. And now if I say that he's doing that he says I'm mental and that he isn't when I know fine well he is. Now I pretend he isn't doing it even when it's clear as day. He lives with me and we are together all the time. We don't work I am disabled due to an accident. What annoys me the most is he lies to my face an I just accept it. I don't talk to my family or friend about it as in the past I have an was made out to be mad again by him so I look like I'm crazy so I've stopped that. I don't know how he pays for this as I don't see any of his money. But again we live in my flat I pay all the bills and food shop every time. It confuses me that he can do this. It makes me mad that he dose that in the bathroom every 30 mins. What can I do. I know I should be done with him but I'm stuck
