What's the Rule?

I know there is some lesbian rule about when ex lovers can be friends again, is it after there is one ex between them? Or is it they each have to have an ex between them?
It all gets so confusing. We need a handbook.
Sometimes the only cure for post-romance blues is some Joni Mitchell music, something chocolate or at least some pastry with a nice filling, and maybe a bottle of wine.
That and excess sleep tend to heal the broken heart.
The best part is you can loll around the house looking like shit and all of your friends understand.
Given the right food, music and mind altering liquids and/or solids, even a Pity Party can be a pleasant soiree. I am planning one this evening with a friend who is recently unemployed and also loverless and depressed. I have an apple pie and some drumstick ice cream cones, a bottle of champagne, two bottles of beer and a few other chocolate goodies that should assuage our mutual angst.
Misery can be fun. That's what I am shooting for.
