My husband has been a functioning alcoholic throughout our marriage so for more than 20 years. He’s a good dad, a kind man and a hard worker . He drinks at least a bottle of wine most nights and usually just passes out on the sofa. I avoid him every night and sleep in the spare room as I can’t bear seeing his feeble slurring self. My 18 year old daughter is embarrassed to bring her boyfriend home as my husband tries to engage in slurred wide eyed conversation with him. My son refuses to admit there is a problem and takes his side . Ive begged him for years to get help but he refuses to admit he has a problem. I feel nothing for him anymore . Should I leave ?
