I appreciate the feedback from everyone. Forum sisters are the best.
My procrastination, I think, is due to a combination of ambivalence about the decision, and guilt about upsetting a 71-year-old woman's applecart. (Especially one who lives on a small social security pension.) Add to that my deciding to sell the house a couple of times before and then backing away. I need to be sure before I do this again.
What's different this time is that I have a plan. And that plan includes a fall-back for roomie if she wants or needs it. I also have plenty of lead time and my son has agreed not only to help me clear out my house (at least the big stuff), but to move my roomie as well. And I have already made a good start by moving a lot of my favorite belongings to my St. George place.
Went downstairs to talk to roomie this afternoon and she was asleep. The next I heard was her leaving to go to her granddaughter's house. Tomorrow. I'll tell her.
Really.
Honest.
