Hi, JennaKS,
Welcome to the Forum and it is the right place to come and share your story with lots of people in similar situations.
Your partner needs to get on some of the on line meetings for AA, CA etc, if he really does want to give up everything. He has to want to do it for himself, and he doesn’t have to talk, he can just listen.
Try and persuade him to go to the Doctors, at least it’s a starting point and would show you he really wants help.
Keep in touch on here and look after yourself as well.
Take care.
