tsuwm, you've given me an idea for fleshing out the "stages" a person goes through when they're moving through this universal challenge of falling out of love. Thank you!

I guess, then, we would have (1) Lover, (2) [possibly] Beloved, (3) Estranger and (4) Anagapesis.

What's the word for the person experiencing anagapesis--the Anagapetor? And the ex-Beloved would be the Anagapetee? LOL
