Your continuing ultramarathon theme is a good reminder. While we communicate a few times a week despite her being out of state now, and it's pretty friendly, I still feel like my wife is sprinting toward divorce. She occasionally mentions that she needs to have the divorce paperwork notarized and things like that (which, to be honest, I could do without being reminded of, but what can ya do...)
When this thing first started for me, my W was in fast track mode. Sometimes I've found myself wishing we were done by now. Your W may find herself liking the positive interactions and has to bring up the reminders for her own benefit, too. IOW, she may feel a little conflicted, and uses the self-convincing out loud to get herself back on track.
