Yesterday we took the dog to the vet, and everything was cordial once again. She was still wearing her wedding ring. At one point, she did initiate talk about how her work was going, and I engaged her about that. Other than that, all other talk was just small talk, and my words were "scarce".
She did her laundry, and after she left the house, I found that she had also done my laundry. So then I texted her a "thank you, you didn't have to do that." She responded with "it's ok. you're welcome."
