Pick up your wallet, your keys and walk to the pub. Do not utter a word to her. Return half cut and fall asleep in front of Babe Station on the sofa. Wake up, cook bacon, go out on your bike, stop at the pub for Sunday lunch on the way home, have a Sunday afternoon in the garage/garden/on the sofa in front of the TV. Basically, don't respond to it, just go and do what you want to do. At some point she will break rank and wonder where you have gone and/or why you have not tried to talked to her. At this point adult conversation can commence. She wants a reaction, don't give her one, just get on with things, she will talk to you in the end. If she asks why you are ignoring her just say that you thought she didn't want to talk so you didn't.
You're single aren't you?
