well today went off without a hitch, she came to pick our son up, asked how I was, how my finger was (hurt it at work), and how the appointment went. I told her what we talked about a tiny bit, and then she asked if pastor asked about her and I. I said he did and left it at that. when she leaves i usually give her a hug; she was extremely cordial the whole visit and actually put both arms out to hug me. So i decided to stop texting her and wait for her to get ahold of me; sure enough i got some a lot of texts about random stuff (no R talk) and a "goodnight" just now.
Good job. Just let her continue to initiate communications like this, and respond to her civilly. Do NOT pursue her. If she hugs you, make sure YOU break the hug.
