I don't see anything unreasonable about her response. Wouldn't it be smart to know why you got to this point? Acting out of wisdom sound smart to me too.
You thanking her for not saying she wanted a divorce just made you look weak. You might as well have said "Oh I am so relieved you aren't divorcing me! Thank you!". You should have just tried to understand her point, which was a good point IMO.

It is not things that bother us, but the stories we tell ourselves about things.
