I have a different take: I think she's being utterly insensitive, this early in your sobriety. Or perhaps she doesn't realise how much it bothers you, so she's not being insensitive...but you need to talk to her.
I get what Mark75 related but we're not talking about your "best bud" here, we are talking about someone who shares your home and your life and the lives of your offspring and shared family and presumably will do so forever. So either she knows it bothers you and doesn't care, or doesn't realise it bothers you because you haven't talked to her about it. Which is it?
