Agreed, this appears to be going nowhere.
Floopy, I don't want to sound like a jerk (and now I probably will) but I have been with my wife for about 15 years now. If she brings something like this up, then I know I have crossed a threshold that I shouldn't have. Trust me, every guy wants to think he is in complete control of his life, but in a marriage that just isn't true. Everything you do is a compromise and should be treated as such. It sounds harsh, but it really isn't. I would be miserable without my wife. Sometimes I feel miserable with her, but I know the good far outweighs the bad and I make little adjustments here and there to keep the peace.
I would be lying if I said that my drinking is always in check. I have bad weeks where I drink almost every day. I recognize it before she says anything and react accordingly, but I can tell she is thinking it.
I sincerely wish you the best of luck in this. You may find that there is an easy peaceful way to resolve this, or you may find yourself loading that last proverbial box in the U-Haul. It's up to you to decide though.
