Am I on the right track?

The nagging would be about housekeeping issues. Clothes on the floor, dishes not clean, etc. I'm not a slob, though."

Again, I asked for a no excuses list. If she complained about the housekeeping, then she had an issue with it. PERIOD.

"Usually if her complaint was about my shirt being on the floor, she'd have pants on the floor somewhere else."

More of the... "well she said I did this, but SHE did THIS!". If you keep doing this, and trying to show that things were "fair" between you, you won't get your W back.

"But again, even if she considered my failings at tidiness worse than her own, is that reason enough to leave?"

Yes. I'm beginning to see what she had an issue with. You said that she told you that you always got your way. I can see that. You seem to argue your point to show that you're right or that the things you did weren't that bad because the other person did the same.

What you see as trying to be "fair", I can see it as just score keeping. If I can pick up on that after a few posts, I can imagine how frustrated she would get after dealing with it for over 13 years.

I can almost hear your reply to this, saying I'm wrong, etc.
