As you well know, I'm no expert...

I think the meeting was fine. As you describe it, it was about logistics and validation. No harm there. (I only wish I had the opportunity to validate.)

Scheduling regular meetings, keeping communication open -- no harm there.

About her jumping on the phone, and you afraid of it turning into friendship... Ya, I see your concern, but we have no idea what that is, so let's not mind read or make anything of it. We don't even know if she's going to make a habit of it. So keep the calls short and on point. You had previously set your boundary of "no playing family" and I don't see that any of this violates that, so I think you're fine.

Did I screw up by meeting with her?

I don't see any harm in communications if you stick to the rules, keep the topic on parenting and hold your boundaries.

My IC is telling me it's over, but I'm not phased by that at this time. If I listened to everyone else I would be in the throws of a full blown D at this time . She is encouraging me to work on myself which is good.

You have this completely mastered.

Carry on.
