I am going to refuse to buy more bottled water for my wife.
What do you have against bottled water?
She drinks that much that I can't afford it anymore, so no way
Water isn't that expensive you should let her do what she wants. It's not nice to tell her what to do.
That's my job and I'm concerned about her health.
She can drink bottled water if she wants to. If you have such a tight budget you should sit down and work it out together.
