My ? Is should I just get off the phone and no talk at all or what. Did I make mistake tonight?
I don't think it was a mistake to tell her about D3 doing well at the movie.
When your W gets on the phone, sound upbeat but like you're kind of in a hurry to get off the phone. I know this probably sounds like playing games or fake to you, but try to trust us here. You did great in how you answered her questions. You don't get off into details.....keep it brief and a little vague. Don't sound rude or cold, but you have a busy life now with a full calendar. She will want to know what you're doing and who you're doing it with, etc. But, that's not her business now.
As far as continuing the dinner after dance, that's a call you will have to make. It is an opportunity to show your 180's.......especially attitude with the kids in public. OTOH, your W is wanting to eat cake here and keep this little part of "normal" left in the family. If it were me, I'd probably use the opportunity. See how it goes.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
