Many thanks to all who replied. I really do appreciate the messages. And yes, I'm very happy we're neither married nor have any kids, that would truly make it so much more complicated.
I meant 6-8 bottles of wine.
And while it may sound incredulous, he really does lay off the booze during the week. He doesn't hide his drinking, and fully knows what my thoughts are regarding it, but weirdly enough this is something he is honest about. He doesn't go to bars to drink, he might have gone to bars in his younger years, but not for as long as I've known him. Not even for a date in the beginning of our courtship. Restaurants yes, bars no. Too crowded for his liking.
I know it may sound too good to be true, but he has cut back the drinking during the week. I guess it's because of this I'm still with him, and probably indeed hoping against all odds.
