It's good to hear your update. I wonder if your wife invited you over or started to change because she had been in another relationship that ended? Or she's lonely? Or perhaps she feels just a little sorry or guilty but not enough to come out and say it. It's good that you're not letting minor or indirect signals change your plan since obviously those aren't sufficient. I think the response you get from her when you tell her you're ready to file will reveal her feelings much more clearly.
