Hi Boo
Welcome to the Forum where you will meet many people in a similar situation.
Cocaine is an evil drug that makes the user equally horrible and it’s hell to live with. I think they are aggressive because they are guilty and take it out on the ones closest to them, which is hard for us, the name calling is vile.
My Son is an addict alcohol and cocaine, and has been for about 12 years, he does try and get clean and sober but I don’t think he tries hard enough, gives up too easily. He says I don’t understand, which of course I don’t. They have to want to give up and get in the road to recovery, it has to come from them.
Has your husband said that he wants to give up? There are lots of on line meetings that they can do on Zoom, and some face to face meetings were open, depending on area.
Take care of yourself first, and keep in touch on here where you can chat freely and not be judged and it helps to rant too.
Take care.
