Thanks, AS. You're absolutely right. I do always have a tendency to focus on the negatives, always have. I didn't really take the time to realize how much positive there has been lately, in regards to how W is treating me now. we are getting along much better, much more cordial.
I replied to her in a text saying, "thank you for the card. It was very thoughtful of you." I probably could have done better, but that was all that I could muster up at the moment. She didn't reply.
