I went from W saying "I don't want to be around you" - "I don't want to have anything to do with you" to going to dinner with family, laughing joking - then having me to her apt, and talking to me for 2 hours.
You know - I believe it's the only way to maintain sanity is to detach. It is incredibly hard.
I do not answer when W calls, period. I call her back or drop her a text, period. I want to make sure that I'm as unavailable as possible.
I don't know how to make it any easier, other than to keep yourself busy. I got tons of books from library, rent movies, work on house, clean, do laundry, not much outdoors stuff this time of year! Take kids bowling, skating, out to eat, so on.
Just don't sit and stare at the phone or email! I know I talk a good game, but it's just as hard for me!
