Oh gawd, so familair. My STBXAH told me he HAD to drink with the boss and the other dudes in the field he is in to "build cameraderie". Even though he was gettting along just fine with his boss and work mates prior to getting sh*it-wrecked. But that ridiculous excuse was basically him trying to give himself a valid reason to booze it up. They ALWAYS look for a valid reason first, before the belligerence and the "Whateva! Ah do whut I WANT!" attitude comes out. And it always does. Every drunk is a selfish drunk.
I got the speech too about how successful he was going to become, and how it would be a shame I wouldn't be there to enjoy the riches with him. My take? A rich drunk is just a drunk who now has more money to spend on booze. We all know by now that that never leads to anything good.
Good for you for making a decision to put your happiness first.
