Is there a word for mutual enabling?

The Siberian Siren and I are so dangerous for each other. We always have budgets when we shop, and if we're together, both of us exceed them, every time. We both recognize the problem, but I don't see us fixing it any time soon. Her girlfriend is too butch to enjoy that kind of thing, and tells her to shop with me. All my other, perhaps (but not necessarily) more sensible girlfriends are either too booked, too butch, or too tired.

I'm lucky so many of my meals come from StartupCo. Money that I budgeted for food has gone to makeup and clothing.

From the Dept. of Rationalization: Nibs bitched at me for years because she doesn't like the smell of Angel. I was over budget because I picked up some Chanel Chance at Ulta. (The SS cried, "It's not my fault!") Be careful what you wish for, Nibs.

The rest of the haul from Ulta:

• A couple of nail colors and base coat from OPI. I tried it at the SS's. It's good, durable stuff.
• Eyeliner - Urban Decay's Perversion. Hey, I ran out. Like you do.
• Mascara. I was... nearly out. I think.
