What ditch her now and find a whole new Pain in the Arse.Why not ditch her now and save the trouble later? Find yourself a newer, more agreeable, model. I think it would be far less cruel to do it now than during the zombie apocalypse.
The fact is the scenario you are envisioning is highly unlikely. It is much more likely you will bug in and survive in your fortified position. Are you going to throw her out of her own home?
And no Im not gonna throw her out, may have to eat her later,lol "yeah I know ,here its comes"
