Our financial agreement includes WAW doing what she has always done - buying groceries etc for the family. So on Sundays, she will be doing that and if things go ok, she will also be making dinner on Sundays as well.
I see no problem with any of that as long as I am not needy, clingy or persuing when she's around the house. There are some people here who would be thrilled to get to the point of there WAS having contact and keeping communication open. No point in making things worse by telling her I want nothing to do with her.
I will see how I feel regarding time with WAW over the next couple weeks and during our vacation and act accordingly.
If I didn't know better, I would say her behavior is possibly coming from feelings of guilt.
