Thanks everyone for your supportive comments.
I don't feel like he has the right to gamble with his life like that. I've tried explaining it to him, but he said I am being controlling and wanting to change who he is.
It's a mess.
I have no money so I cant go home, even for a short break. We can't even afford to buy a cot yet, so things are very stressful financialy.
Yes, he threw the phone at me, and my ear is still sore from the cut on it. I've only seen him have an outburst like that once or twice before and that was about five years ago.
I love him dearly but I feel like this relationship is costing me so much already...throw in my morals* about drug use and I feel like I've given everything.
*I really hope I don't offend anyone. I know some people on BH use drugs socially and that's fine...each to their own. I'm only concerned about my DP and his health issues etc.
