STAR TREK ANGEL:
There is no magic formula for "fading". It depends on your circumstances and everyone is different.
I planned it carefully and also made sure I had friends outside!
I'm single and worked so it was easier for me. I just picked a Thursday night meeting to deliberately miss and that was the start of my "fade". It was wonderful to stay home and watch CSI. It was winter time and what a relief not to go out on a cold night when I was dead-tired from work.
What a light, free feeling I had!
I wasn't really "missed" until a month or so and I had the excuse of a death in the family. I ignored the greeting cards.
Just don't let anybody corner you. Screen your phone calls, etc. and look before you answer the door. Good Luck.
