He just tried to re-engage me in the fight by saying "I don't know why you felt the need to insult me after you had just told me you wanted to be cordial".

This was this morning.

This is also after he made the switch to telling me all of a sudden that he wants a divorce, too.

I avoided it and am proud of myself. All I said was "I don't want to get into this now". And left it at that.
