It takes much longer to quit drinking than just few days. I was in a relationship with functioning alcoholic. Thankfully he was not ever mean or rude to me, he was a quiet drinker but still that lifestyle didn’t match mine. I don’t drink. His attempts to quit always failed. Of course he begged me and what not and promised etc. But the bottom line I finally left him 6 years ago and am happily married and have a wonderful life with someone who has no unhealthy habits and treats me like gold. And to my knowledge my ex still drinks. Sure some people quit but it takes a ton of work and sadly most addicts never fully quit. Or become addicted to something else. Don’t go back. You deserve better
