Geeze, SuperDave. I know you've been dealing with this for 20 years, but you've only been here for about a week. Seems kind of rash to me that you're leaving her right now. Can't you at least give her an ultimatum first? Or suggest counseling (I don't particularly like counseling, for many reasons, but it works for some people).

I just hate the thought of you wandering the streets, getting hassled by a bobby, run over by a lorry, and all that rot.
