JSD, My sitch was very similar, during the initial break up she went on and on about wanting to life life to the fullest, different directions, etc. etc. As it turns out, she is still doing the same boring things with an OM with many similarities to me and I'm the one that took the different direction and is now living a fuller life at my tropical location. Think the reality of that is just beginning to hit her.
Being kind is always good advice and just focusing on becoming a new you is enough, you don't have to "show her", that would be considered pursuing or she'll think just that , that it's only a show. Become and stay a new you, she'll be watching without having to be shown.
Many WAS do believe that things will be the same and with their added benefits after a D and don't realize the impending impacts until way too late which is why they convince themselves to go through with it. That's where the "friends" catch-22 comes in. Some of it is showing her that there's no easy street, some as payback for hurt, but on the flipside the underlying hope to reconcile. See that again and again on these posts. Good luck on the new you, Ronjon
