I’ve been there sadly. Just recently my husband overdose and I barely saved his life.
My husbands father also was an acholic and 4 years ago he got clean, but my husbands upbringing was rough and may have contributed to his own addiction.
My husband just recently started to struggle with alcohol abuse ( I myself found driving around at 11pm at night looking for him as he tried to stumble to the liquor store).
This past week his alcohol addiction caused him to relapse on heroin where he almost died.
He always convinced me he had the problem under control and not to tell his family as it would break him.
Long story short, his family and my family all know now and it is like a weight lifted off of my chest. His family helped me get into a rehab and have been my support system through this.
I suggest you ask his family and your family for help. The more support you have the easier it is to help him. You are not alone and don’t forget that.
I wish you all the luck and hopefully he get help he needs
