I am actually not really sure what's going on with my brother-in-law. He didn't actually check himself into detox. Since then, he has been calling and texting the husband, asking for help. The husband drove to the brother-in-law's place and tried to pick him up, but the brother-in-law didn't open the door, or respond to shouts from the street. 

The husband is done with his brother. Right now my mother-in-law is in the hospital. She will need help when she gets out. We are traveling to California this weekend for that. The brother-in-law is making his own choices. He has to deal with these consequences.
