The art of distancing a "lover", or good friend in an orbital space. Not too far, not too close. When they get too far, you pull them back in, when they get too close, you push them back out into the "safe zone". This keeps the person in your life, exactly where you want them.
The bitch wants to get married, and I don't. The sex is great, but I'm just not ready for commitment. "Safe Zoning" her would be to ignore or be non-committal to her emails and phone calls and when you've totally pissed her off, send her a dozen roses, fuck her, and repeat the cycle.
