It's worth a thought. Pity's usually just a form of affirmation. The other person grumbles, and we say, "Yes, I totally understand," in the most compassionate voice.
I'm guessing, though, that you just may have to wait, and keep showing her the positive changes you've made. At least she's not talking D. That's a blessing. And her attachment to and possessiveness of your laundry is really kind of sweet. I'm wondering what would happen if another woman stepped in and offered to do your laundry for you: OW Laundress might get her hair torn out.
It's a little baffling, but, all in all, in good time, I think you're likely to get your happy ending.
