Affair discovered 3

A FB FRIEND REQUEST!!?? I received one from W tonight. Maybe just because I sent her an email tonight asking to be added as a parent to son's FB kids' messenger account. Is it a requirement of the kids account that any parents on it are also FB friends? Can't imagine W wanting a genuine friendship, and if so this isn't the way I'd want to start one. I don't want to be her FB friend anymore.

More details if interested:
I've been slow to respond to W about this conflict around talking to my son on days I don't have him with me, but the night of my last post I did ask her if she was open to talking about it. No response from her that night. Met with my IC the next day who advised me to email a proposed schedule and have a shared calendar for when I plan to talk to son during the week. I dropped the ball on that but did make a calendar before next dropping off son with W. At Monday morning dropoff, W looked to have just woken up. I asked her to talk about scheduling times to talk with son, and she asked to talk about it later. I said ok, and that in case we didn't talk about it, I had planned with son already to call him the next day after I got off work. No initiation of contact from her until then, so I texted the next day asking to talk to son as usual. She replied after 10 minutes that he didn't want to talk to me. Later that night she sent me a FB message which was a request to add me as a contact to son's kids messenger account. We had never mentioned the option of a messenger account for him to each other, though it was something I was considering myself. I thought it would be a less reliable means of contacting him, and I had other concerns about it too, age appropriateness, privacy (my own from W). Tonight I emailed her saying I'm open to trying it out, but that I want to talk to son about it first in person, and be added as a parent to his account. I wish W would actually use words to communicate with me about this. She's just dropping things in my lap with no explanation or discussion.
