mza8, I wouldn't read into her actions about the house. You already know that she wants to sell it. She is anxious about it because it is what she needs.
As for the emails about the electric and gym mebership, she could have contact the electric company but it was much easier for her to ask you. The gym membership is telling me she want to do things own her own and have no ties to you, but don't worry about that.
Keep up the NC and short contacts with her.
It is hard but neccessary.
