Trailmix nailed it: "The fact that he cannot quit drinking on his own indicates a problem."
Our "lines" become so blurred with addicts. We accept what most would never find as acceptable. The fact that we're even counting!? Damn I wouldn't even drink that much orange juice in one evening or weekend... just sayin' to bring some perspective!
Honestly, looking back... I'm deeply thankful for 2 things: I didn't get married or have children (we were very close many times) with my XAGF. Leaving that relationship was HELL without those obstacles.
When you begin counting their drinks, there's a problem. When you begin, doubting... there's a problem. When you see the RED FLAGS -- don't ignore them like I did, save yourself... now.
