lost8, 2x4 time. You said: "my detachment in my mind has worked" Wrong. Detachment means you wouldn't care who she was texting. What she said to them. And you certainly wouldn't have confronted her about it.
I know it is hard. I know especially when things look like they are moving in the right direction you think she should have given this up entirely. These things are rarely that clean and easy.
DBing is about giving her space and letting her figure her stuff out. It feels like that is what she is doing. Confronting her on this was a setback. DBing is about patience and self-control.
