I wouldn't recognize any date she doesn't first. It falls under pursuing and appears to be an attempt at manipulation by making her feel guilty or trying to get her to remember the good times. Read the 37 rules again.
Also, don't worry about the fear of not showing more interest. I feel that too, it's a fair question. But it isn't true. She is in a TOTALLY different place then you, read more threads by WAS's. when and if the day comes she has feelings strong enough to reconsider the D she will let you know. She's not going to walk away from the potential of a happy marriage with someone she's close with and loves because he respected her wishes and took care of himself. Broadcasting how you feel can destroy that process however as it forces her to keep her defenses up and forces her into the role as the WAS.
She is trying to walk away. The more you pursue the faster she walks. Stop chasing so when she is far enough away to feel safe and looks back she likes what she sees.
You know this, now keep doing it!
