So aggravated

I don't understand how people can be so addicted to something that they would actually steal off of their own mom/family to get money to buy it. As we have walked through the past month with my husband out of work, knowing we didn't have money to buy his alcohol, I don't understand why he wouldn't have taken this time to get clean. It is sad and depressing and I am just beyond frustrated. There is not much to a person who will steal from someone for this purpose.
