It's not cake eating. She's just doing what she wants to do which is what you should be doing too. Just because she's doing something that you can't control doesn't make it cake eating.
"I texted W and said "do you know who's truck this is in front of our house?" and received no answer what so ever. W ignored me."
She went to a music concert right? She could very well have not heard the phone. Mindreading.
"It was a guy she was on a date with to the show with OUR friends."
How do you know this EXACTLY?
"She is being incredibly selfish, self-centered, disrespectful, and rude, to me and our family."
Didn't you do the same when you had your A? What makes this any different?
"I don't know how to set a boundary here without being condescending or a jerk. This is not ok with me. At all. How can I convey that in a way that preserves my dignity and protects me?"
You can talk to her about it but you can't force her to do anything.
"Should I just not address any of this at all? Let her do what she wants? Let her treat me and our family like this?"
Treat you like what? She's living her life the way she wants to which is what everyone wants. You are the one who allows the bad feelings to come up in you. You're just getting a taste of how she felt when you carried on with the OW. It doesn't matter that you stopped your own A. She had to deal with all of that too.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
