Sorry to read that, but you seem to be doing well. I'm starting to think, that even when our spouses do have 2nd thoughts, they feel like they can't go back. Maybe it's pride or something. Every time I thought my W may be reconsidering (being nice, helpful, asking me to do stuff, etc), it was soon followed up with a gut punch. And yes, bringing up stuff from the past is their way of justifying their current actions/decisions.
When a relationship ends, the person that ends it only remembers the bad times. While the person left behind only remembers the good times. The truth is likely somewhere in the middle, but both people are usually too stubborn to admit it.
