I'm a young man still living with my family. My problem is my father and we are getting tired of him. He is addicted to meth. The symptoms are getting worse and so is my life conditions.

His hallucinations about our "plans" against him, his cynical and negative delusions about my mom, his envious talks about successful relatives, his inability to support the family financially, his arrogant expectations, his loud yelling, his rude and aggressive reactions to my mother's polite requests etc...

He starts to yell and look for an excuse to start a fight whenever my mother goes out with her friends, there were times that he actually chased my mother. My poor mom has cut off all of her relationships with her friends (all of them female of course.) I totally trust my mother and know that she is a righteous and religious woman. It's my father who is a delusional fool, thanks to Meth.

Worst of all, i recently discovered that he is a deviant, hedonistic pervert too. I think he sleeps with street pros. This one is something i can't accept. My view on him has changed forever, i have no sympathy for him now.

Also, I think one of his new habits is spreading gossip and slanderous nonsense about my mom, though I'm not sure. I think this way he takes revenge for all the negative attitude towards him in the society and relatives.

Quick facts about the guy:

• He has been taken to rehabilitation facility once. He resisted and ended up fighting with the rehabilitation facility staff and getting beaten.
• Detoxification 5 times. Each time relapsed after 2 days.
• I had so many arguments with him and yelled at him, now he believes I'm the new 'enemy', along with my mom.
• His self-confidence is too low.
• My mother looks down on him and humiliates him in front of us.
• Has no friends, expect 1 corrupt junk.
  

How should we cope with him? Should we change our behaviors? How?

I'm 100% certain that he doesn't want to leave meth. Should we move to a separate house and leave him alone? Divorce is not an option.

Thanks for your patience and time.
