Maya, he's just grasping at straws, still looking for one last thing to blame his life on, so he can think it's not his fault, that he doesn't have a problem.
My husband gave me similar lines at Starbucks the other day, where we met to discuss our legal separation. He actually suggested that we "sell the farm, the horses, everything and buy a big house in town, and be like normal people." Huh? Booze fried your brain, buddy? I'm normal, last time I checked, YOU are not, booze man!
Glad you are doing well! Onward!
